I made a slightly smaller one that I used to mount on my dad's Waltons store brand mid arch with the same wheels in 1987. I derived endless amusement watching the little miniaturized mechanism stay upright as the wheel spun away. In certain light, it looked incredibly like a real one I saw on an AEC bus hub!! You might find this merchandise of interest, including a watch, glass and even a frisbee!! These pics were sent to me by a nephew of the founding brothers of Engler Instruments of New Jersey USA, who I got in contact with seeking more information on the company and it's hubodometer. He has the same surname as it happens.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
