Another mystery gun "help" thread

Thanks Harold. Yes, that’s exactly how it operates to break it down. I’m quite curious about this shotgun and wouldn’t be surprised if you’re really close as there was a Belgium Meteor in this collection as well.

It appears to be a Lefaucheux action, used by several companies. It is a very strong action that apparently uses a dual underlock system.
