I did something really stupid. I didn't notice my C&R was ready to expire until the day before it was due to expire. I called the BATF and was told "sorry" nothing they could do about it that I would have to reapply. They said I was sent a notice that my license was about to expire but I never received it. Well it has been about a year now and I haven't reapplied. How long am I required keep my old C&R log book? From everything I could find in the regulations I can't find anything that requires me to retain my logbook once my license expired but until I know for sure I'm hanging on to it. Does anyone know if there is a requirement to keep my logbook for any length of time? Also, should I decide to get a new license would I need to transfer data from my old logbook to the new one or should I just continue using the old one again? Thanks for any help on this.
