Steve,
manufacture date Likely mid 1917..later than that the Imperial Navy went to the type 2 for the land based Naval units in Flanders.These were without stocks. The Germany marking indicates ww1 surplus sold to the US in the mid 20's.
At any rate some time after 1918 as George says. I say mid 20's because it took some time for Germany to settle down to a viable exporting economy and establish importers in the USA such as Pacific Arms. They then tried to sell anything available if import catalogs are any indicator.
Establishing a value is a little difficult. Tom Armstrong's valuation is really too strong on the date he made it...That was in a very strong economy. This economy is getting worse by the day and I see genuine Luger bargains pop up more and more. Cash is king so to speak and many collectors are having difficulty selling at all.
If I were given the opportunity I would buy this stock immediately for $2000. There is a guy I know of who has a really poor example for around $4500. Only someone who knows nothing about Navy stocks would even consider it.
Another guy I know of has one for $2500-2800 I forget but it's an outright fake. He knows it but is waiting for a cash cow I guess. Several people have bought it and returned it. I can't understand people sometimes...I guess it's all about the money.
So if the economy is as bad as I think I would guess your stock might bring $2500-3500. Might not too..I just saw a very respectable pigskin Luger holster that no one bid $350 on and a couple years back it would have brought $650 easy.
So who knows?
