Parts luger help

[Dave Sanders]

I am being offered this parts luger, and I mean parts. I'm not sure if any part on it is from the same gun. It functions fine, shoots fine, takes down fine, but is such a mish mash of parts that I wonder as to its aprox. value. The hold open is un numbered, the toggle pin is numbered, and the fireing pin is numbered andis WWII style. I didn't take the grips off, but they are in good shape and no million dollar chip. Thanks for any advice you may give.
