Well..Not much else to say about it. There has to be a Crown N or other Nitro proof on the pistol somewhere. Side of the breechblock usually. It was a German requirement. Taking the pistol apart might let you look it over a little more closely.

Take the rust off the magazine.

The stock is an enigma without either better photo's or more detail. It can't even be evaluated as it is.
The pistol either actually. More information and or better photo's are necessary but from what I see..The pistol is likely $7-800 as a shooter.
The stock might be $200 unless something else about it comes to light. Really need to see the attaching iron to wood fit..Closeup of the strap slots etc. It could be an original period stock..not desirable as a Military serialed Crown S proofed stock.
Again, I would put some distance between the two of these. Sell the stock to someone. Forget about keeping them together. Might not bump into trouble but it's there..waiting..
