There is usually a screw on the top of the receiver in front of the hammer or a pin through the side of the receiver holding the firing pin in.
I have a Eastern Arms (sold by Sears and hardware stores) Manufactured by Iver Johnson as well as others. It is a 16 gauge single barrel shotgun model 1929. The firing pin is removed by cocking the hammer back, there is a set screw at the top of the receiver , when removed the firing pin can be removed from the hammer side;watch for the spring. Installation is the reverse.
A oistolsmith can either find and install the parts, or possibly make them. However, the cost of repair will likely equal or exceed the value of the gun.
you can get parts for most guns at Numrich gun parts corp. they are on line, and send parts out very fast
Yes, Iver Johnson made a 10 gauge Single bbl. I currently have one and have just finished putting it back together. I also have a 12 gauge just like it that shows patent dates in 1902 but the 10 is older by several thousand pieces. All parts a pretty much the same except for the pivot pin. There is very little difference otherwise. Hal Hal500xl@aol.com
There are companies that make generic bridge pins, so just visit your local Guitar Center with your guitar and they should be able to help you.
It gives you front , center and back of the green. It can't measure to the pin. But you can move the cross hair to the pin position and this will reflect as center. I have a SG4 and love it.
The center of the head pin is on the 20th board.
Well I'm assuming you mean the Champion 12 gauge single shot? If so by the cocking pin there is a lever that moves vertical left from right. Turn the lever right an the barrel breaks. (The lever basicaly right on top of the stock )
Any alterations to the pin is considered 'bad' by most veterans. Although there was a change int he green center a few years ago. It was dropped as a part of the pin. However a Canada flag pin as the center should not be an affront. Best to ask a veteran.

To remove the slide from an Iver Johnson TM22PB Trailside: (1) pull the slide back (2) push down on the take down button (top of the slide in front of the rear sights) (3) push the slide forward (if you did this correctly the recoil spring is pinned and the slide will not be forced closed). (4) take the side grips off (5) drift the mainspring housing pin out (6) remove the mainspring housing (the spring is pinned so there's no worry of anything launching). (7) take the slide off Cheers
