Did I get Ripped Off?

Lugers are often made up from parts and the function of them can vary depending on the parts fits and the skill of the maker. At a gun show this afternoon, a fellow walked in off the street with a byf42 luger that he claimed to have purchased from Gart Sports in the 1950s. It had several replacement parts including the barrel. The grips had been prettied up with a pocket knife. It appeared to be a sound shooter (that looked as though it had been fired several thousand times) and he was asking $300. Because of the wear and mix of parts, he was not successful in getting $300 before I saw him wander off down the aisle. One week ago, a completely original (all original parts) 1929 DWM luger in 70% finish sold here locally for something around $500 or over plus shipping. The owner thought it was a WW1 luger and shot his reloads through it, damaging the right grip--he thought it only a shooter but it actually would make a decent collectible. I hope the buyer treats it as such. You can get a good price if you search, but it takes time.
