Adding a "Victorian" settlement

I’m planning a mouseguard campagin with an idea to introduce victorian elements (such as the great mouse detective from disney) into the game. I was wonding what I need to do to introduce firearms, I’m thinking more blackpowder than more modern victorian firearms.

Any ideas?

Firearms of that era are just really slow but easy to use bows for their utility…

Must say I like the idea of introducing some Victorian elements…especially the great mouse detective.

Use the Bow stats, maybe have something like +1s for an Atk once a Conflict to represent the slow process of reloading
