a guy i work with *older guy, drives the big rig for the store i work for* has a WW2 M1 his dad gave him way back in the day. he's looking to get the gun registered here in cali but the serial number on the gun has been ground off. to what extent i dont know but as i said he wants to register the gun cuz he doesnt have any paperwork for it, or whatever you need to register a gun *im not in the gun crew yet, hope to change that soon* so i told him id ask my buddies *i.e. OT* about what could be done to fix his problem. any ideas guys?
