I have had a C & R license for a number of years. I agree with the reply from Chuck H. If any gun is particularly named on the published list by maker and model number, sometimes by a range of serial numbers, but not always, OR if the gun can be definitevely prooved to be over 50 years old (by date codes or serial number published charts or other means) it is also eligible. I have never seen in the booklet any gun eligible because it's over 50 years old stated to be NOT eligible for any other reason. Now, don't confuse any C & R eligible gun with full auto regulations. A 50 year old MG is eligible under C & R licensing rules, but still must meet other full auto rules, and I don't even know what they might be since I don't handle any, only that the C & R license alone is not sufficient for full auto or other restricted items. I would like to see more details about the manufacturer being specifically disqualified in BATF regs, I have never seen any such regs.
