Curious about firearms that could fit well in a "steampunk/victorian" setting.

[Diego Wolfwood]

I've done a little looking around and found a few that I think would fit well:

Mauser C96/M712 Schnellfeuer
Bergmann-Bayard M1910
Borchardt C-93
Luger P08

I think most western firearms would fit well too, but I'm mostly trying to discover obscure old firearms, such as the Bergman. I had no idea it existed until I ran across it while browsing.
