Steve,

Thanks.

The point is that "Acier Compound" sounds like a registered trade mark to me, but I can not find it in any of my lists.... I think, but can not proof it was held by Pieper. If that is the case, he may be out of luck. Pieper did have a cartridge company and often made proprietary rounds for their guns...

To the best of my knowledge the Pieper proprietary cartridges have never been completely cataloged. Here is an example:

However, I could be mistaken. It could just as well be from ML or Neumann. That is why I asked about the other markings on the gun.
