    A quick Web search suggests that it was made by Crescent arms.
    If you can post a picture someone with the same gun marked with another trade name can help you.

    If you don't get an answer, I have used clay to make an impression of the firing pin. Spray the hole with a release agent like WD-40. Take a "worm" of clay with a strand of thin copper wire or string inside, Press it in, then stick the action in the freezer for several hours to harden the clay. Pull out with the wire or string. Or heat up a section of thinned to approximate diameter plastic coat hanger and force the soft plastic into the hole.

    Thread pitch will likely be some odd ball gun size that you will not find at the hardware store. Hot plastic rod technique works better for screws to get a thread idea. I would just drill and tap to the next common size for cheap truck guns.

    You can look at firing pins in the schematic. I made several single barrel shotgun firing pins out of an aircraft bolt with a file and an eggbeater drill as a kid.

    also look at Stevens, H&R, and Iver Johnson's for pattern/parts

    I've checked all the normal sources for parts ,shotgun belongs to a friend and it was missing firing pin and retainer screw.I hoped someone would have the actual parts to measure .I know the screw thread is obsolite but thats no problem to modify .
    I'm a machinist of 30 years so making the replacements will not be a problem. Always good to try and get actual specs if possible then go reverse enginier way.
    I've got H&R shotgun and a Iver Johnson and they do not match the Crecent made shotgun.

    Sorry, do not have one at hand- but I think the spelling is Powhatan (I happen to live in Powhatan County VA)

    If it is marked Powhatan Arms Co, Richmond, VA, it was manufactured by Crescent Fire Arms (1893-1930). If it is marked Powhatan Pat. Aug. 11, 1896, it was made by W H Davenport Arms (1891-1910).

    POSSIBLY sold by the Watkins- Cottrell Hardware company in Richmond (Their store had a big double barrel shotgun sign on the exterior- in business from 1911 to 1972)
