This numechron was purchased for parts, but with a little tinkering, cleaning, and oil it is working. This model has a lever to prime the clock you just flick the lever, a few times and indicates that it is an early numechron. Pennwood replaced the priming lever with a priming knob later on. It has an open rotor that made it easy to clean, and oil. The patent on the decal on the back indicates it was manufactured prior to 1935, and the second wheel is black, the red numbered second wheel began appearing in 1940. This is one of the earliest Pennwood clocks.The Bakelite is in great condition without major scratches, cracks, or nicks. The cord had been replaced when I got it, with a fiber wrapped cord which is what it would have had on it originally. It is quiet and keeps excellent time. It is 7 1/8 inches in length, 4 1/8 inches in height, and 3 3/4 inches in depth.

This model was also manufactured in a white marbleized Bakelite. This clock I found out via NAWCC was designed by Peter Muller-Monk.

Thanks Chadokoin for the informative update.

    The "Patents Pending" statement on the decal probably indicates that your clock was made in or before the first part of 1935. Pennwood was pretty good at keeping the info on the decals current. Their numeral wheel patent (no. 1,990,645) was issued in Feb. 1935 and that patent no. appeared on all clocks they produced subsequently. The open motor with starting lever also indicates a very early clock. Maybe the earliest Pennwood model with a bakelite case? Great find!

    Thanks Chadakion for the informative update. I updated the story of the numechron to reflect your information.

    Chadakion, this isn't the only one I have with a Patents Pending tag, this one does also.

    Discovered the name for this model is the Leonis it appears in a 1934 ad.
