1939 P08 with Nazi and Imperial markings

[justsomeguy]

Hello all,
I recently acquired a P08 after desiring one for many, many years.
Specifically I was looking for one with a high probability of a war time capture, which I think I have.
I'm hoping from the pictures, the experts here could tell me more about the history of this pistol.

I could be wrong but it looks like both Imperial and Nazi eagles on the receiver which I found interesting.

Does this mean anything specific?

Also the mag has the Imperial eagle and I was told by someone more knowledgeable than I that it was a Black widow mag. Can someone confirm or correct that from the pictures?

Thanks!
