Thanks for the info guys. Sure thing on the pictures.
Got a few questions if anyone can help.

Anyway to accurately date it to date of manufacture?
Did the Poles make it, are is it originally german?
Any guesses on its value?
Most importantly, can I shoot regular current commercial 8mm in it?
After originally posting, I looked it over again and found an interesting cartouche on the stock. Anyone recognize it?

Thanks again for the help.
