DGALLO,
George Andersons along with Jerry Burneys sage comments, I would like to add that your original leather cup that holds the metal nose of the shoulder stock is a very hard find for Luger collectors. Your holster looks OK for an original holster of this vintage. I don't see shoulder straps. Did you get them with your rig?
When looking at Lugers I often look at the 'Locking Bolt' first to see if the gun has been messed with and yours looks good. I only see the million dollar chip on the left grip, by the thumb safety, is not so good. But don't let that worry you. You done did yourself proud.
Don't worry about price. With the internet and the rarity of this Luger and its accessories, the price is very difficult to pinpoint. Currently, my SWAG would be $5,000. But I wouldn't be surprized if it would currently go for more. The stock and leather elevates the price. Matching mag?? I forgot what you said about the magazine.
The manufactured numbers don't really reflect the scarcity of these weapons because so many have been destroyed for a number of reasons over the years. Do not restore or restraw this weapon in any way, it looks to be all original and should be kept that way. As a collector, it would be nice to have a matching dated holster, but its not necessary.
Again, congradulations on your purchase. Nice pictures.
