Smith & Wesson 78G restore project

you could possibly vee out the crack and fill it with jb weld then flush it off clean out lettering again with dremel tool etc,that would disappear when painted,wont really be any stress on that area when assembled and being used.

had one or two these back when first took up pistol shooting many years ago because they were made as trainers for the real pistol of which i had for many years,weight and balance,handling exactly like the firearm,there were quite a few in pistol club shooters hands as trainers we could use at home,but as you say bit rare these days as they had issuses with a certain part that we couldnt get as replacements etc,made few these parts but cant remember now exactly what it was other than it was brass,i did make few these but was 30 years ago,they were all painted but that one not factory paint job thats for sure,used to repaint them with black stove paint then put them in oven at 100 degree f for bout hour to harden paint,they came out like factory finish,frames made of zinc alloy so wont anodise anyway,prob why factory painted them i would think,really neat pistols tho,Ron may still have or be able to source parts and seals.
