Gray was located in Hartford, CT, just a stone’s throw from here, from roughly 1950 through 1970. feel free to correct me if you personally know otherwise. I have come across very little original Gray literature and equipment in my 13 years here.
There seems to be very little information on the internet about this company, other than this nice archive.
If you or a family member worked at Gray, please drop us a line.
