Today, I purchased a unit marked 1918 DWM serial number 5755d, on the Rock Island Auction. The mark looks like this: S.D.IV.3.52.R. Can anyone shed any light on the meaning of this unit mark. There is no sear safety on the Luger; however the magazine is an aluminum bottom mag. Any help will be appreciated.

Thanks,
Mike
