What is this part called...

[siegersallee]

Hi alanint and Norm,

Yes, this photo is of my pistol which I know is a real (all parts and grips marked) Erfurt...except for the mag which is period correct.

My question was about another luger that I have been eyeing.

The seller says that his pistol is an all matching Erfurt; however, I saw that on his pistol this pin did not have the Erfurt stamp.

So now that I know for sure that this pin should be marked, I do not think his pistol is worth what he is asking.

I just wanted to be sure, that's why I was asking this rather involved question.
