I have added a description of another Synchronomains synchronous mantel clock to the Synchronome page. The link is

An unexpected feature is that the clock had been neatly modified a long time ago so that it runs backwards.

Hi Les
Yet another nice, chunky-cased clock. I like those ones with either a discreet seconds hand or a red-white flag showing that the clock is working.
Old ‘church’ friends may still have a kitchen Smiths wall clock with a black outer case and yellow-gold-coloured Arabic numerals and hands. It was/is in their kitchen and have never seen another one with the same colourings. I always admired it.
However, I did own one briefly with a red outer case and white numerals and hands I think it was and bought that for a good price in London quite a few years ago. I’m pretty sure that one was self-starting and just a knob for the hands.
Thanks for this one again and its interesting write-up.
