British Markings: Do they lower the value of the Luger?

Comparing M1 rifles and 1911 pistols with British proofs to Lugers with British markings is comparing apples to oranges. The M1s and 1911s are martially marked and were issued to troops while so marked, while the Lugers were given the British markings after cessation of hostilities, and so are civilian markings. The M1s and 1911s are considered legitimate, unaltered military weapons, while the Luger is only marked for import purposes. Most such Lugers are not very collectible, and are little more valuable than shooter quality guns.
