Don't forget that at the Manx National Heritage iMuseum visitors can find and read newspaper articles on this and thousands of other topics dating back to the eitheenth century. If you haven't yet visited, you should! Open Wednesday to Saturday 10am - 5pm (open until 7pm on Thursday evenings).
It has been some time since my last post on this blog, but we have not be idle! A great deal of background research has now been undertaken, and we have diagnosed in considerable detail the patterns of wear in the movement of the clock. Our findings include:
- none of the pinions are original; this empirical observation was confirmed by analysis of the composition of each metal part by x-ray fluorescence spectroscopy;
- the pinions are, for the most part, of very poor quality;
- their design is entirely consistent with that common to many other 15th and 16th century turret clocks, suggesting earlier replacement on a like-for-like basis;
- many of the components can be associated by metallic composition with a group we are currently assuming to be original;
- the clock very probably dates from the second half of the 16th century: we are awaiting the results of radio carbon dating which we hope will confirm this;
- the clock incorporates some eccentric and unique design features (c.f. English Church Clocks 1280-1850, C.F.C. Beeson, 1971);
- scars now found on the frame are consistent with mountings for a verge escapement underneath.
