Since I am not selling this Luger I have no issues posting the price:
Luger P08: $1250 shipped to my door (includes new barrel and gun smithing as well as any other work performed)
Holster: $100 shipped to my door
Prussian belt with belt buckle: $74 shipped to my door
Grand total for the project: $1425 (rounded up to include cents missed).
Not bad considering prohibited examples start in the $1200 + range. If you add tax (if applicable) as well as gun smithing costs to bring the Luger into the restricted category you may go into the $1600 price range. Artillery lugers seem to sit in the $1700 range and up. I have seen one priced at $3500 and from what I examined of it first hand, she is a real beauty to be sure! Swiss Lugers, are just insanely priced around, and sometimes above, $2500.
Original holsters from WW1 that are dated and in decent condition start at $450 and up. I would dare not force my Luger into an original holster.
I have yet to see an intact WW1 German leather belt with belt buckle but I am sure they are out there as I have seen original uniform jackets floating around at gun shows. I would imagine original leather belts with intact and functional belt buckles have to sit around the $150-200 range ?
All of the pieces I picked up can be used for re-enactment with no fear of damaging a period item (minus the Luger).
All I can say is that putting away $20 here and $10 there really adds up over a year.
