The last "on scene" auction I attended was billed as a "firearms auction", I guess because that's all that was to be auctioned. Lots and lots of real common stuff that sold for way too much. I went only because there was a Spreewerk P38 and a Krieghoff Luger listed. I got there early so I could inspect. The Luger was a "parts gun", not a serial number matched on that pistol, the P38 was no better. Both looked like they'd been run over with a half track. Keep in mind, this was about 12 years ago,,,,,, the Luger sold for $1350,,,,,,, the P38 went for $1200. It was plumb stupid! I haven't been to that sort of auction since! I won't waste my time!
