I think of it this way, a luger pistol is a historical 'weapon'
As is, let's say......a grenade.........which is a 'weapon' also
You wouldn't want to keep a live grenade in your collection, but rather, an 'inert' one, but just because the 'weapon' aspect has been taken away from it, doesn't fault all the history and authenticity from it. Just the same as a pistol, although its main 'weaponary' purpose has been taken away from it, it can still be a very fascinating piece. Just the way i look at it
