Screw Head
 

Need some info about the screw heads on the side of the receiver. The larger one is the hammer screw and the smaller one with it is there to secure the hammer screw. Is this correct? I have one that someone has put the small screw in first and then the larger one is on top of the smaller one. If I backed the hammer screw out 3/4 turn then I can remove the smaller screw and then tighten the hammer screw to the correct position and put the smaller screw back in its correct position. I have not been inside a Parker farther than to remove the stock so not sure what holds what and don't want to mess anything up. Thanks for your advice. Gerald

You can try that method but DO NOT take the larger “hammer” screw out too far.
Once you take it too far out and hear the hammer “snap!” You’ve gone too far and the stock will need to be removed and reset the hammer and screws.

To make sure nothing is messed up, the action really should be removed from the stock and the hammer screw/hammer removed.

Thanks. The small screw is only there to secure the hammer screw. Is this correct? Would it be safe to back the hammer screw out 1 3/4 turn to allow more room to remove the small screw?

I decided to take it to Bill Schwartz. He said someone has put it together with the hammer screws reversed. He is going to disassemble and clean it and assemble it correctly. This is a high condition GHE 16 gauge from 1930. I can't imagine someone doing that, but I guess if you have a screwdriver and you see a screw you have to stick it in it.

The small screw is a locking screw intended to keep the hammer shaft screw from turning. The hammer shaft screw has rotational forces on it when the hammer is cocked, or the gun is fired & the small screw locks it in place to prevent it from backing out.

Now Gerald, you know we're going to need some pictures of this "high condition" gun when Bill is done. :corn:
