Jason,
No limit on numbers
No non C&R in book
Previously owned guns do not have to be entered, matter of fact shouldn't unless you sell.
There is no defined limit on the number of guns you can sell, but it must not be a business.I don't know how they define this and if there is a limit on selling. They may come to look at you if you are selling dozens of guns a year. You can only sell to another FFL if it is out of state. You have to tell them how many you bought and sold when you renew.
Face to face sales at shops or show, the same just give a signed copy for an eligible gun.
If your state allows face to face sales between individuals I don't believe you need the C&R, but I have yet to test that as there weren't any in Hawaii and I haven't been looking since moving.
