Here's a pulsynetic master clock and susequent lots of Gents, Smiths and Synchronome slave clocks from the 50's to the 80's. It's an online 'easylive' auction only, and collection in person is by text-message appointment slots for virus reasons. I know there are fans of these on the forum.
Ther'e also a few interesting radiograms if you care to hunt.
(no connection with sale or lots).
