The C&R FFL allows the licensee to send to and receive directly from other FFL holders those firearms that are classified as C&R. No having to have the gun shipped to another 01FFL for transfer to you. It avoids transfer costs and delays. Plus many businesses in the trade offer discounts to C&R holders as well as 01FFL holders. The records are open to inspection to LE at any time. The 4473's and bound book records that any gunshop makes out and keeps when you pay them to transfer a gun to you are also open to the same inspection. A private party transfer should include ID and a receipt to protect you in the event that the firearm does show itself to be stolen. It's not a good position to be in with a stolen firearm and your answer of where you got is " a guy at a show". Even a personal record of your guns for insurance purposes is a still a written record. No, you don't need one, it's just a convenience to have one. My 01 hasn't drawn any black helos yet:>)
