a while back i bought a cz52 at a gun show. i recently recieved something in the mail from the dealer i bought it from saying that he wrote the serial number down wrong and the ATF is bothering him. he asks that i call him and tell him the correct serial number on my firearm. Can I get into any legal trouble if I refuse? I value my privacy and would prefer not to correct his sloppy record keeping if I have that option. I don't really want to lie and say I can't read the serial number cuz its such an old gun, i'm just thinking of not calling him. What should I do? basically, is it his problem and not mine? or am i required to provide him with the serial number for a gun i purchased from him over a month ago?
