Some clues eliminate some systems.

Cocking dogs eliminate it from being a Baker system (think Lancaster 12/20, etc)

It’s obviously not any Beesley type system

It’s obviously not a H&H system


Possibly a Boss type easy opener? A pic of the internals would confirm.


Daryl,
Do the ejector stems have constant pressure on them? When the gun is disassembled, are the ejector stems sticking out like they’ve been fired?



No visible pin for holding the bolt system for the Smith easy opener…

It could be the later Churchill/Baddock patent of 1936 “jumping Jack” system that was a redesign of the Smith system?
