Re: 'Not an 1892, after all. (Embarrassed!)
No silencer, so no lawyer necessary. The button like thing looks like it would fit through a leather strap???. The dovetail cuts, I am not sure about. The front one has a strange elkhorn, but I use the vernier sight when shooting. Perhaps they're for a scope? It would be mounted awfully far forward, though. I'll get better images up later today. Thanks.
