No public database- sorry.
What year was the Butler derringer made. Serial 22500
We need a make of derringer.
I was told by a gun collector that a five digit number on an imported derringer is not a serial number- it is a lot number ( a serial number should be at least 6 digits) what about the proof markings on the gun? can this identify the company or date or just the country of origin?
No way to answer without a serial number and complete description
100 or so
Only what someone is willing to pay !
You don't provide a serial number.
Impossible to answer without more information.
