Pivot breech 'Flobert' pistol.
Proofs are German
The 6mm rf Shot cartridge was one of the standard chambering in alot of these pistols.
Could also fire the 6mm rf ball ammo.
Rifled barrels were provided for those chambered in that shorter cartridge normally.

The sporting goods import catalogs from the late 1800's & early 1900's usually show several different makes and styles.
Makers aren't always listed, instead a catchy catalog name plus a number was assigned.

Perhaps a makers mark is visable under the wood, but beyond that I don't know who mfg'rd it.
Is it marked Korinski/Erlangen anywhere?
