A firearm in Germany lies in a cabinet whose resistance grade is set by the law and the firearms authority, not by your feeling. New cabinets are at least at resistance grade 0 under EN 1143-1. How many handguns and long guns each grade takes, and that heirs do not inherit an old grandfathered status along with it, is in the guide Gun cabinet grade 0 and 1. In the overview Security for collectors this is the one collection for which the cabinet is not a matter of taste.

The collector price beside it

What a firearm can be worth at auction is in the text The most valuable weapons and in the profiles there, from the Colt to the Marengo sabre, which is however an edged weapon. For your collection: number, caliber and the papers make the difference between a firearm and a documented piece. The papers do not lie in the gun cabinet with the firearm. Ammunition and firearm follow the rule from the guide, not an idea of your own.

What time does to it

Moisture starts rust, the wrong oil turns gummy, wood moves. You store it the way the cabinet and the piece can take, and you check on a fixed rhythm. A rust spot you keep silent about is a dispute later.

The folder

Each firearm one line: type, caliber, number, document. The license and the correspondence with the authority go in the document cabinet. The authority remains the place that decides when there is doubt. This text is the way to secure the collection, not legal advice.
