I've only run across one Bradford TV, about two weeks ago. It was in a pile of garbage of a gutted house and partially crushed. It was a 23" color combo with thumbwheel controls in the lower part of the crt bezel. I'd guess it was from around 1970 and must have migrated here because I don't recall any Grant's stores in this area. I wasn't going to dig though a wet pile of moldy crap to investigate any further.
