I may be wrong but when I had the license, I had C&R guns in a different category than the ones I bought straight out with regular paperwork, or FTF. I logged in the C&R guns, therefore I had to log out the couple that I ever sold to individuals. Otherwise, I treated the other guns like I was a regular owner in that case. STill good to keep/ get receipts for private sales of anything that is in your name, somewhere. There was no connection between my private guns and the curios, I was not a retail dealer or anything, obviously, so if you don't have the guns in your log, they are not of the same interest IMO as you did not use your special status to get them.
