frogwalking- I made some changes to my Pedersoli .58 - changes that could benefit the 12 bore. The fences, while being shaped correctly, are not very 'active' due to poor lock geometry, too-high hammers, and too-high nipples. Too, the bolsters are not shaped correctly at the rear and are rain catchers. I re-filed mine and installed shorter nipples. Have to watch that the main springs, letting down just a bit further due to lower nipples, doesn't hit the bottom of the lock mortise. I also got rid of that horrible cheek piece & their nasty stain and refinished the gun in Danish Oil (Tung).
I really do wish I'd been able to get one of the 12'as, but have to make do with a little .58.
factory hammer/nipple/fence relationship. Breech rain gutters filed out at rear of plugs. They were closed tot he fences as received.
altered gun with lcoks panels blued
Refinished rifle - locks, hammers, tang, trigger gaurd all blued - were bright chrome-like finish. Stock refinished with Tung oil- no stain.
