Keith,
Our own Lloyd owns a sweet little 16 gauge boxlock ejector by that firm, and, I’m thinking he researched them a bit when he got that gun. His is old, but, it is a looker, and he has used it in the past to great effect on grouse.

I’m thinking a few others here own those guns. Perhaps a few here can point you in the right direction.

Side note, did you ever do anything with your Dad’s Charlin?

Good luck.

Best,
Ted
