CZ2506,
Please get back to us after you pick up the gun. I'd be interested in knowing more about it after you get it, especially if you could post a picture or two.
I'm curious about it b/c of your description or memory about it using a clip instead of the side magazine box mentioned by eldequello in his reply.
I'm knowledgable about some older military weapons but don't know about any variants to the 30/40 Krag except the one with the side mag box.
