Requirements
Inflict 10,000 damage with unique Mojave Wasteland weapons.

Behind the scenes
The name of this achievement/trophy is a reference to section 27 CFR Section 478.11 of U.S. Federal Firearms Laws, which states, "1. Firearms which were manufactured at least 50 years prior to the current date, but not including replicas of such firearms; 2. 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 3. 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," are "Curios and Relics", meaning that they may be exempt from certain other regulations in U.S Federal Firearms Laws and that they can be shipped by mail directly to a Curio & Relic license holder without having to go through a gun dealer.
