1938 Erfurt?

[Military Engineer]

Hi,

Hope all is well. I've been a member of the forum for a while, but haven't been on in quite some time. Hoping now to avail myself of the expertise here.

I've come across a Luger that I'm having a hard time identifying because the parts seem to be a mishmash a bit. He is asking a little over $1000. I just wanted to get an opinion, on a number of things if possible. Yes, I will be inspecting it; he just lives 2 hours away so I wanted to have an idea before I go up and actually see it. He is confidant and is willing to let me shoot a mag or two before purchase.

Just so we're clear, I've tried iding it using "The Standard Catalog of Luger", by Aarron Price, 2006 edition (ISBN 13: 978-0-89689-411-2)

Seller says 1938 Erfurt Luger and that by all accounts, he is the 3rd owner (He is in his 70s, got it from a friend also in their 70s who got it in Germany from an older German gentlemen). The manual says Erfurt stopped making them in 1918 and was involved in the reworks [consider the double date Lugers], but there is no indication that it was necessarily reworked by Erfurt or anyone else.

Is there a reason that the bolt block/extractor would be replaced with one 20 years older?

Opinions on general appearance?

Next, I'm having trouble with the proof marks and I'm hoping that someone out there can ID them. Center looks like E/63, and right looks like the Nazi mid-acceptance mark (signifiying '37-'39 make) but I'm not experienced enough to say. Any suggestions? What would the one on the left be and is there a reason it would be a 2nd E/63?

Bakelite grips are indicative of a Black Widow, but the other markers for a BW don't seem to be there. Grip replacement?

The price may very well be fine, or it may be too high, so I'm open to input. My concern is just identifying this. I'm thinking a 1938 Mauser Police issue, but I'm too new to be that specific or confident.

Any suggestions from the experts?
