KM optical sight ... opinions please..

[Luc]

I found this on at a local fleamarket at the Belgium coast. It is marked with the typical Kriegsmarine eagle. But what is it..?

This is the same as I have.
Take a look at this link:

As you can see, the front part of your sight is missing.

If you want to sell yours then please let me know.

Best regards,
