Early EH
 

This is an early EH 3 frame I dont have a lot of other info on. Obviously well worn and stock head has been pinned. I dont think I have ever seen the screw placed in front of the sear pin though. Identical one on the other side. Any knowledge or speculation as to what these might be? Thanks.

A mystery. I doubt it is anything good

That is a real head scratcher. And I cannot imagine what function it may serve. Likely just some hack method of fixing a problem. Or maybe even perceived problem.

Additional fix for the cracked stock. Maybe the cheek screws were not working out.

Cocking indicators?

A totally unnecessary access hole for oiling?

I am trying to think of what could be going on there given what is behind that area mechanically. That being the hammer/sear engagement. IF there is a function to that, the only thing that makes sense is Lefever’esque trigger pull adjustment. The screw has an offset post on it that allows the sear to engage the hammer notch more or less based on the position the screw is turned to. Thus effecting trigger pull weight.

Do you own this gun? Or buying it? Or just saw it online and grabbed the photo?

GB Item 880847920; I like early EH's but this one looks like trouble. I too questioned where the screw or "pin" impinged inside the action. Looked like the front of the sear, but couldnt figure out how or why. I've seen similar "extra" screws in different locations associated with various ejector experiments, and some single trigger installs, but this one was the first I've seen like it. Thanks for all the thoughts.

A number of guns have been asked about over the years seen on sale sites. People ask about certain mysterious modifications and what they could be. So far as I know, nobody has been willing to take the plunge, buy them and find out.
