I have this old monster that I recently picked up. I don't know exactly what gauge/bore it is, possibly an 8 or 10. The barrels are just over 41 inches long to the breech plugs, it is a hook breech. The only markings are T or D Baker on the locks, London on the barrel, London or Birmingham proofs on the underside. Crown and scepters over V and crown and crossed scepters with the usual letters around them. Butt plate, trigger guard and remaining furniture are of cast nickel and engraved, trigger bow has a running dog on it. It also has two barrel keys. I have never noticed this feature before on any other guns.
Sadly, some moron, stamped spurious Wells Fargo markings in it (A real problem here in Montana, they think it makes any shotgun more valuable).
I was wondering if anyone knows this maker well or any of their history? I will try to post pictures but have not been able to figure it out.
