i am collector since early corona, researching anti nano technology, where are you in the world? i work with a lot of dealers who have been collecting for over 20 plus years, it was a business, i am now turning it into a hobby as i have other work commitments ...i am still a collector. I literally buy collections 20 at a time from other collectors, it is a gamble buying an unrestored machine i have developed pattern recognition so i know what i am buying and even if i know a machine may not be great i am always on the hunt for rare glass electrodes ...
