The date of its movement gives an indication of the date of a Temco synchronous clock. The Mark IV movement was produced from about 1933 to 1938, and the Mark V movement from 1938 to the late 1940s. The notes on the Temco page have been updated.

The January 2012 issue of ‘The College Mathematics Journal’ is a Martin Gardner Special Issue. It includes three papers on flexagons which were introduced to a wide audience 50 years ago by Martin Gardner. For my paper see Gardner 13-cmj011-014-pook
I welcome comments on the content of my website and, where appropriate, try to respond to them promptly. Comments are moderated, and only accepted if they are relevant and appropriate. In particular, comments that are advertisements are not accepted.
A Smith synchronous electric granddaughter clock, which I have previous referred to as Model GM 30, is actually a Gibraltar, date range 1935-1939. This date range matches a known date of 1935 for one particular clock. I have updated descriptions on the Smith page to include the correct model name, and apologise for publishing misleading information.
My research into synchronous electric clocks is an ongoing activity, and I always correct errors in clock descriptions as soon as I become aware of them.
I welcome queries on synchronous clocks. If anyone would like a private response, rather than a public reply to a query, please indicate this in the comment. I will then send a response by email and not approve the comment for publication.
I have updated the subpages on various makes of synchronous clocks to included photographs of most of the clocks described. As before, more information can be found by clicking on a link. i have also added descriptions of several more clocks.
Does anyone know what has happened to the Flexagon Lovers group hosted by Yahoo? The site is still there, but there have been no new postings since the beginning of the year. A posting I sent in January has never appeared.
I’ve added the following quotations to the Quotations page.
