Can someone tell me about this magazine?

I tried to get some clear pictures and I think they turned out good. As you can see, one marking is a partial strike? Those are all the markings on the body. On the wood bottom is a very small "3" and a "8" It came with a code 42 1939 Luger. I know its not the right one for it from what I have read, but its what I have. Thanks for any help!
