This was the best variety of 400-day clocks we've had at our small gathering.  From the basic to the sublime.  Superb examples of Grivolas clocks were inspected and discussed.  The JUF bell striker is also a very rare item.  The early bandstand, the Sylvester, even the humble Kern and Link and the Badische acorn pendulum clock revealed interesting issues to talk about.  References are from the Horolovar 400 Day clock guide by Charles Terwillinger 10th edition and from the Torsion Times, the newsletter of the NAWCC torsion clock chapter 168.

The first two pictures are of an acorn pendulum and DRGM movement of 1910, plate 1041, wrongly described in the guide as 1890.  The early bandstand  has solid pillars, a rectangular movement with the corners cut off and lovely gilt hands. Patent Angemeldet by JUF,  plate 1471
We were all in awe at these fine examples of Grivolas clocks.  The Torsion times has a good article on these movements by John Hubby.  Each model A, B and C is exhibited here as well as different pendulum designs.
The Ormolu clock is type A, the white marble garniture is type B and the green marble type C.  The type C four glass is taller since it houses the tallest of the pendulum options from the Grivolas range..
This JUF striker  was rescued without a base.  It is difficult to get a glass dome which fits the traditional base size.  In this case one was not available and a blue marble base made to suit the best available dome.
Quite often strikers had patent numbers on the dial, perhaps this is the latest in the series.

The humble clock just to the left is probably  a Kern and Link approx 1932, plate 1667.
Lindsay gave a talk on patents and is holding up one he got from the British Patent office by Leslie in 1793, containing a torsion pendulum arrangement.  Lindsay is going to build one to see if it works! Some patent dial examples also shown.
A pinwheel 400-day clock by Sylvester - one of the rarest types of 400-day.  This also has a patent dial, castellated gallery, unusual suspension and two balls!  What an oddball!
Techniques for brass polishing were discussed and this one was done using a paste product called Wenol, a German metal polish with good success.  It's 50% finer than Autosol, commonly used for this purpose.
