Research before Scrap -- Painful learning

Your thinking about selling old used parts that may or may not work, been setting ,remember. The place with the parts probably were contacted by the company and bought up all the old repair parts for certain makes and models knowing there would be a market someday. I know a CB radio supplier that did that. He almost went out of business during the slump but managed to survive and he picked up inventory from closed down factories and started selling "new" old parts, and the older they get, the more expensive they get. Today he is one of very few places to still get original factory parts for some models. Same way with anything else.
