I'll give you $500 for it and pay for shipping, there was only 6 made and you have the 8th one that left the Enfield factory in Germany during WW2.
If the stock is in good shape and the cartouches are still present I'll up my offer to $450.
When you turn the gun upside down does it say "made in a factory"
If so you can guarantee it was in fact made in a factory, by people as well.
That makes it a collectors item.
Now when you cycle the bolt you should hear a metallic sound of sorts.
Also the stock if it is wood, this would have come from a tree.
