To be recognized as C&R items, 478.11 specifies that firearms must fall within one of the following categories:
a.Firearms which were manufactured at least 50 years prior to the current date, but not including replicas of such firearms;
b.Firearms which are certified by the curator of a municipal, State, or Federal museum which exhibits firearms to be curios or relics of museum interest; and
c.Any other firearms which derive a substantial part of their monetary value from the fact that they are novel, rare, bizarre, or because of their association with some historical figure, period, or event.
Firearms automatically attain C&R status when they are 50 years old. Any firearm that is at least 50 years old, and in its original configuration, would qualify as a C&R firearm. It is not necessary for such firearms to be listed in ATF’s C&R list. Therefore, ATF does not generally list firearms in the C&R publication by virtue of their age. However, if you wish for a classification of your particular firearm under categories (b) or (c) above and wish your item to be listed, you may submit the weapon to the Firearms Technology Branch (FTB) for a formal classification.
Please note that firearms regulated under the National Firearms Act (NFA) may be classified as C&R items, but still may be subject to the provisions of the NFA. If your C&R item is an NFA firearm (e.g., Winchester Trappers) and you desire removal from the NFA status, you must submit it to FTB for evaluation and a formal classification
