Is there any way to identify this?

Its a long barreled hand gun with a small handle, and deringer style trigger. On the barrel there are the letters B G, and under that U, each letter has a crown. The barrel is too small to fit a .22 shell in.

All I have of the gun is the barrel, handle which lacks grips, trigger, shell ejecter, hammer, and the long piece of metal that serves as a hammer spring inside the handle. It was given to me by a family member when I bought a .22 derringer from him, and I just always wondered what it was. Any clues would be helpful.

Thanks

Just as a wild guess, from the description I'd say you have a Flobert style parlor pistol.

Probably in .20 caliber, for shooting primer-powered lead balls at targets.

European made, from the proofs, probably Belgian.

A parlor pistol for sure.

Caliber is probably 4mm Zimmerstuzen once used for indoor shooting like air guns are now.

BUG proofs are German.

I saw a reprint 1910 Alfa (German sporting goods company) catalog that had a variety of such guns.
