This is an epiphany. I suddenly realize the point that Klaus is trying to make and see its relevance to the comments made by Dwight Gruber regarding the itinerate inspectors of military arms.
We collectors are used to referring to inspector’s marks on military Lugers of that period as being “Erfurt” or “DWM”, but in reality the proper designation of these marks should be “military acceptance” only and be relegated to the production facility to which they are associated.
Erfurt was a government arsenal producing military Lugers, so they rightfully had their own government employed military inspectors for their products. DWM, on the other hand, was a commercial firm producing weapons for the government. It follows that DWM should not be in the position of “accepting” their own products for the government. Therefore, there had to be a government entity that performed this function…to wit, the Spandau arsenal that was in proximity to the DWM production facility in Berlin. This implies that there are
no DWM
military inspector’s marks or proofs.
Therefore, it is evident that all military Lugers that were produced by DWM would necessarily bear “Spandau” inspector’s marks and proofs (as opposed to "DWM"). Consequently, the LP08 barrels produced by Erfurt bear the “Erfurt” power proof, and those very few LP08 barrels manufactured by DWM bear the “Spandau” power proof.
Hope I got that right
