Q: Is there any interest in vintage dental things? My brother recently retired as a dentist. He has several pieces of furniture and equipment that belonged to an associate who retired when he was over 90 years old. He has a gray wood laboratory cabinet marked “American Cabinet Co.,” an old sterilizer that resembles a dishwasher, some old hand instruments and many old bottles of chemical supplies. If there are collectors of such things, how can I contact them?
