BTW, there is another factor in collecting, whether guns or anything with a 'serial'.
There are those who collect only certain serials. True! Rich person of course, but with Lugers, there is more chance of getting great shape serialized item than with say a motorcycle.
Back in 1998, I owned a rare Harley-Davidson motorcycle. I knew it was rare and collectible so I advertised it in
Hemmings. I got a half-dozen calls from that ad, one guy wanted rare color combination, but weirdest was guy wanting certain serial number. I was wary, but he rattled off the number he was looking for, and mine was not it. He went on to explain that he collected one of each model Harley but only with that serial number...Weird, but true collectors
are weird...
