Bought a hunter arms hammerless double trigger in an auction. No side plates, no firing pins, serial number 46329 under that a C O stamp. Barrel markings, left side Hunter arms co. marker, Fulton N.Y. Right barrel armor steel. It has the square window on safety switch. Hopefully I can pin this down, so I can order parts, And get an exploded parts view so I can see what I’m missing. From one of the parts distribution companies.
