$50-$75.
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?

Sorry, not enough information to answer. Even with a brand name, many low cost firearms were imported from Germany in the late 50s early 60s, and there is little information published about them.
