How can you find out if a pair of Thomas Jefferson dueling pistols 972ab is stolen?
In most cases, when purchased, pistols need to be registered with the ATF. Contact a local gun dealer and see if he could help you trace down ownership. * The ATF doesn't keep a registry of pistols, only machine guns, short barreled shotguns and other destructive devices. Your local police can find out if the serial number has ever been reported as stolen, but a lot of people who have had a gun stolen don't even know the serial number, so it doesn't get on any lists. Anyway, what you are asking about is a modern "commemorative set" which doesn't have much value so wouldn't have been grabbed by someone wanting to pawn it and certainly wouldn't be stolen by anyone planning to use it.
1093 US patents were granted to Thomas Edison in his lifetime, as well as several hundred patents in the UK, France, and Germany. Many of them, such as the "light bulb" were ruled invalid in a federal court, due to Edison's having stolen and copied materials from others and claimed it as his own. Second alteration. Using the term of "stolen" regarding patent disputes maybe not that accurate.
