I don't know where to start. There are various sellers online but $2,000 to $4,000 is quite a bit of money to buy unseen. Which are the most trustworthy sellers and what should I look for in buying a luger. Seems to be: Date and number made, percent blue and bore, percent straw, and matching magazine or not. Can I hope to buy a decent piece for around $2,000 or more? Any advice appreciated greatly.
