Erfurt with British proofs

[Dave Sanders]

Interesting. I have seen other similarly marked 1915 Erfurts on the net. There are no other British proofs that I could see other than the barrel marking.
I saw one just like it on Simpson's, but yes, most likely a combo.

As Bill stated, Erfurt did not make Lugers in 1915. Your toggle train is Erfurt but the receiver is DWM.

At some point your Luger was summitted to a British proof house for proofing, possibly due to repairs. Always interesting but not uncommon.
