Need help! Some kind of Polish dagger
Hi guys, I would like a little help with this one please, a bit outside of my knowledge. The guy that brought it to me says it is Polish WW2, but I have no idea. To give some idea of scale, the total length of a sheath is 9 inches from end to end. Odd fleur de lys insignia on the handle. Sorry for the poor pics, working with a flatbed scanner.
Some idea of value would be great too, as he is trying to sell it to me.
