You gotta wonder what good that would do. Once the registry is over, a particular gun could be sold legally x number of times without being registered. What would be the point of out dated records. As it is, there are many guns which do not have any serial number or identification. Sure, they supplied ID stickers if a gun didn't have a serial number, but many people didn't bother putting them on or they have fallen off. So not sure what keeping old records would accomplish. But hey, it's politicians.
