The holy grail of electric clock movements--The Hansen Synchron C4 bottom-set clock movement Model 33-232 (NOS), complete with the 43-RA 110v AC motor, knurled mounting nut and minute hand knurled nut. Takes all clock hands designed to fit the C4 movement. Sweep second hand shaft has the correct 2-56 thread. Original cardboard packing sleeve only removed to take photos of the movement.
I understand that the knurled mounting nut can be removed since it is pressure fitted to the outer non-moving shaft but would caution anyone to take care while doing removal. Once removed, the C4 can be used for the older 4-hole mounting system used by vintage clock manufacturers such as Glo-Dial, ENCC, Swihart, Lackner and NPI. Don't let the brass mottling distract you. This is normal for the all-brass movement as they age. It will not affect the operation in any way.
If you are into vintage neon clocks, you know that operational C4 bottom-set movements are hard to come by. I have set a starting bid of $99.
Read my seller rating and bid with confidence. This is the real deal.
