I'm at a local hamfest a few years back and this fellow has a nice Drake R-4B sitting on his table. I carefully look it over (without touching) and determine it is a worthy piece cosmetically. As I inquire about a little history from the seller, he grabs the radio, spins it upside down and places it on the table upside down. In doing so, he drug the top of the cabinet across a staple imbedded in the table, scratching the hell out of an otherwise pristine piece. From what I experienced with this chap, and what I see regularly on all ebay, etc., people generally don't seem to know how to handle objects to maintain them in a pristine state. Finding vintage pieces in "fine" or "mint" condition is exceptionally rare. Some people can buy a new car and have it looking like it's ten years old within six months of leaving the showroom.
