I have a 1918 Gladiator Field Grade 12 gauge. I have a broken firing pin, and also a destroyed front trigger plate retaining screw (see linked pic here https://goo.gl/photos/tLVEXGXaTvUkSLUm6).
Of course I have searched the net extensively to try and find replacements, but have had no luck. Some sites, such as "Bob's Gun Shop" http://www.gun-parts.com/firingpins/ may have these parts, or at least the firing pin, but with no pictures and limited knowledge, I'm afraid to take a guess.
Can anyone direct me to where I can find these parts? The firing pin more importantly. A replacement screw would be nice, but I have a temporary replacement already on the gun.
