thanks chaps. Seems it is a bit of an orphan for information. I doubt mine makes 450 fps , more like 250 on a good day but it intrigued me - and thats enough for me :-) ------------- old enough to know better |

Been getting chat gpt to do some research on it. Can you post picture of the box, gun,gun markings and serial number and I'll reopen the conversation. Its been quite interesting so far but not over fruitful. Relevant info ive found so far and edited ( ive been exploring avenues but the lack of specific info is a bit of a hassel as there seems to be very little info) Import & Collaboration History of Marksman Products According to historical records, Marksman Products did not necessarily build all their own air rifles — they often imported or sold airguns from other established manufacturers under the Marksman brand name: Blue Book of Gun Values Imported/Distributed Brands Milbro (Scotland) – Marksman imported and sold some Milbro airguns, including pistols. Blue Book of Gun Values BSA (England) – They imported air rifles from BSA and included them in their product offerings. Blue Book of Gun Values Weihrauch / BSF (Germany) – Spring-piston rifles from this respected German maker were also brought in and sold by Marksman in the U.S. Blue Book of Gun Values Anschütz (Germany) – Some precision rifles were imported under Marksman’s distribution. Blue Book of Gun Values So rather than Marksman co-designing or co-manufacturing models with other companies, they generally: Imported foreign-made rifles and sold them in the U.S. under the Marksman brand or as exclusive distributor models. Also manufactured their own spring-piston and break-barrel airguns (especially older / simpler designs). Eventually became part of S/R Industries, which also acquired Beeman Precision Arms — another well-known airgun brand — in the early 1990s. Those Beeman rifles were often imported and marketed in the U.S. but built in Germany before the acquisition. Morton H. Harris was the founder and early driving force behind the American Marksman brand. bluebookofgunvalues The Marksman Model 1780 was almost certainly produced in the period from the late 1970s through at least part of the 1980s. There’s no exact documented first or last production year readily available in published sources — but the model number range and the fact that it appears alongside other 1970s/1980s Marksman catalog listings makes that timeframe the most consistent with its appearance on the market. |

Found this doing a history search on marksman The Marksman 1780 Deluxe is a modern (likely 20th-century) break-barrel spring-piston air rifle, not directly related to the 1780 in its name, which references the famous Girandoni repeating air rifle from the late 1700s Which makes me wonder if its possible a 1790 which you can find info on. Deluxe or biathlon on the box? Biathlon is the 1792 model and deluxe the 1790 i believe |

All good. More questions when you got time. Is the stock plastic? Is there a number on the left hand side of the receiver? Where im at. The 1780 is a refrance to the orignal pcp gun from 1700s (Which just thinking about it, ill see if there is a model 80. Could be that 17 is just the tribute) It may be printed on all 17xx guns. Got gpt to search model numbers on marksman guns and apparently its on left of receiver near back somewhere. I'll follow the model 80 thought and see if it produces anything. |

The pat number isnt a real patent number. Cant be found in the usa patent data base or overseas. It is in the right number for air rifles of that era. .chatgpt Why This Happens on Airguns Especially with budget or importer brands (like Marksman in the later 20th century): Factories sometimes marked products with patent references even when the patent was never assigned or the number was internal/foreign. Another possibility is that the patent label was intended to point to a different number, but the stamping was truncated or mis-stamped at the factory. This is fairly common with older airguns and inexpensive sporting goods — they look like valid patent numbers, but they don’t actually match any issued U.S. patent records. Final Answer (no fluff) Model: Marksman 1780 Deluxe Stock: Plastic faux wood (factory correct) Receiver marking: Generic Marksman patent stamp Country: US-market import Most likely year made: circa 1980 (late 1970s to very early 1980s) If you later get: the full box end flap or manual paperwork we could tighten it to within a single year — but with what you’ve shown, 1980 is the best-supported answer. Still probing anvenues with gpt. It doesn't do stuff automatically and you have to constantly send it down different paths that you or I would do naturally. It actually put the date range between 78 and 82. I'll see if can drag up more info while its raining. |

Heres using claude ai to see what resaults would get Im looking for any info i can find on an obscure air rifle. Its the marksman deluxe #1780 I think its from the late 1970's to early 1980's 12:11 1 step Marksman 1780 specifications history 10 results Marksman 1740 air rifle relationship 1780 10 results Good news - I found some information on your Marksman Deluxe #1780! You're correct that it's from that era. Here's what I learned: Basic Specifications: .177 caliber, break barrel, spring piston design with approximately 450 FPS velocity Blue Book of Gun Values Single shot version of the Model 1740 Blue Book of Gun Values Made in the USA with barrel speed rated at 450-500 FPS PicClick Manufacturing Details: Model markings show "1780 .177 cal Huntington Beach USA" with patent number 3-908-626 SpudFiles Marksman was previously located in Huntington Beach, CA until 2010 Blue Book of Gun Values , which matches the era you're thinking of Condition & Usage Notes: The safety button must be fully cocked to lock in place; otherwise it may stay at half position PicClick eBay Users report these rifles shoot smoothly due to their small spring and piston design SpudFiles Current Status: These are considered hard-to-find air rifles PicClick Parts are available through specialty dealers like JG Airguns This appears to be a relatively basic but well-made American air rifle from Marksman's lineup. It's definitely obscure these days, which probably explains why information is scarce! Are there any exploded views of it on line 12:17 2 steps "Marksman 1780" manual PDF parts diagram 0 results JG Airguns Marksman 1780 parts schematic 10 results Unfortunately, I wasn't able to find any publicly available exploded view diagrams for the Marksman 1780 online. Here's what I found: JG Airguns appears to be the best resource for Marksman parts and schematics. Their website has a dedicated section for the Model 1780 Blue Book of Gun Values , and they mention having schematics available for various Marksman models. However, I couldn't directly access the actual diagram files. What you can try: Contact JG Airguns directly - They specifically list the 1780 on their site and mention providing schematics with parts orders. They note "NO PHONE SERVICE" but you could try reaching out through their website contact form. Check if they'll send it - JG Airguns notes they're happy to supply printed copies of schematics if requested with parts orders eBay . Firearms Guide - This is a paid subscription service that claims to have over 27,000 gun and airgun schematics. They might have the 1780, though there's no guarantee for such an obscure model. Since the 1780 is essentially a single-shot version of the Model 1740, you might also search for 1740 diagrams as they would be very similar internally. The scarcity of documentation online reflects just how obscure this particular model is! Can you search for 1740 exploded views 12:20 1 step "Marksman 1740" parts diagram schematic 0 results favicon Fetched Marksman owner's manual vintageairgunsgallery.com Unfortunately, I'm not finding any publicly available exploded view diagrams for the Marksman 1740 either. Here's what I discovered: What I Found: Vintage Airguns Gallery Forum has a Marksman owner's manual posted (from December 2023), but it appears to be a general operating manual rather than an exploded parts diagram. JG Airguns lists the 1740 as a separate category on their site alongside the 1780, which suggests they likely have parts and possibly diagrams, but I couldn't access the actual content. Similar models - There are exploded diagrams online for other Marksman models like the Beeman P17/Marksman 2004 pistol, but nothing for the 1740/1780 rifle series. Forum discussions mention the 1790 model (which is in the same family), but those threads reference looking at pictures from previous repair attempts rather than official diagrams. Your Best Options: Since the 1780 is essentially a single-shot version of the 1740, and both are quite obscure, your best bet would be to: Contact JG Airguns directly through their website (they note "NO PHONE SERVICE" but have a contact form) Ask on forums like the Canadian Airgun Forum or Vintage Airguns Gallery where people have worked on these models Check if the paid Firearms Guide subscription has it (though no guarantee for such an obscure model) The lack of readily available diagrams online really highlights how rare these rifles are!
