For your consideration, here is a Retro 1970's GE Kitchen Brown Wall Clock, model 2149, General Electric. I ran it for about 6 hours.  It keeps good time. It has a little wear on it, mostly on the hanger area in the back. It measures 6 inches square. Item pictured is the actual item up for sale and comes from a non-smoking household. (98.11b-1.11ow)
