Unique chamber marking

[Kaiser715]

Looking at some VOPOs and noticed this interesting Erfurt with a chamber marking I’ve never seen before tried looking around and couldn’t find anything. Anyone ever seen this marking before?

Theres a thread over on Still's Luger Forum if you can find it. I posted a picture of one of these a while back that Simpson had for sale. There was no real consensus on what it was other than a post war marking by someone for something. There are several examples of it floating around in the luger world.

Interesting I’ll try and see if I can find the thread. I’m pretty familiar with Lugers and different unit and police markings but this one definitely stood out I have a copy or writ in steel I’ll have to look through and see if there’s anything mentioned in there.
