You do have an Erfurt mag body with Erfurt inspected base.
Use a glass to inspect the numbers would be my advice.

I tried that but cant see the whole number but pretty sure of the last two digits of 43. Nothing for sure but with that and you saying the clip is legit, it seems to make sense that it goes with this gun. thanks.

From the side the rings on the wooden mag. base look thinner and sharper than most originals and I'm wondering if that part is original or added later. Also it should bear that Erfurt proof stamp.

The Erfurt acceptance is visible in one of the pictures.
