My new antiques - help with Hanoverian markings.

Postman brought me three new guns today.

First is a Rast & Gasser 8 shot revolver, big with Austria-Hungary, and big with the Kingdom of Montenegro which required every citizen to have one (the King owned part of R&G)

He also brought me this nice Prussian precussion pistol dated 1850.
