aw heck, lemme see if i can find a better pic. if i were a machinist, likely not a big deal
it's a 3-legged thing, the hammer pin, disconnector spring and latch spring are all one piece. it's really quite clever, except if it's worn out. i haven't had it off the gun because it is under some tension from the main spring, so haven't measured the disconnector spring arm. the spec is out there, i've seen it, should have written it down. i'm reluctant to try welding on the actual spring because i believe heat can ruin springs. might ruin the temper on the disconnector if i weld on that, but i can get a replacement.
and no, i'm not a metallurgist, either.
