Hi John, thanks for further description and pointers to the other pictures of the movement. Clearly my speculation that the bridge maybe should be above the lever rather than under it is wrong, but someone has to ask the stupid questions ;-)
Nonetheless, it does seem to be a rather elaborate...
Thanks John. Getting a phone camera to autofocus on the cylinder and pin was a bit hit & miss !
I was just looking again at the balance brake mechanism picture that you posted back up the thread. Is there a cutaway at the centre point of that steel bridge under the lever, i.e. a gap between the...
Hi Graham - to confirm, the base of the cylinder does indeed have the banking pin, although I don't see anything on the potence that it would "bank" against. Maybe I'd have to disassemble it to find that, which I'm not going to be doing in the short term. My best attempt at a picture below...
Thanks to all for the replies.
Graham, thanks for those pictures - when you see it complete it's all rather obvious, but I'd not seen the motion work on one of these before. The balance brake lever explanation and picture too. The end of the squared arbor locates into a hole in the dial...
I've been looking for a good representative example of "lace edging" and this arrived recently. The lace edging strongly indicates an early 1760's date (movement and inner gilt case only, so no hallmarks to confirm). It's by William Webster II, rather than his father who in the early 1700s was a...
Hi John, I've previously read both, and will take time to read again in case I missed something, but I don't recall the thread reaching a conclusion about JGH's place in the family, nor that Priestley did, nor helping identify the casemaker whose JH mark is very distinctive.... Andy
Going back to James Gooden Helsby for a minute - I was just browsing "Your Time" by Alan Treherne and there on page 43 is a pocket watch he attributes to James Gooden Helsby - a Massey IV !
Hi Graham,
It doesn't need servicing any time soon so I have no plans to dismantle it. However, it does needs a better set of hands, so when/if I manage to source those , I'll remove the dial and take a picture.... Andy
I picked this up at auction recently. The name on the plate is I M Read, Helston, which I believe is John Mabyn Read, listed as a watchmaker although in this instance he's almost certainly the retailer rather than the maker, given the good quality London finish. I'd spotted what looked like a...
Hi Allan,
Here's Litherland Davies & Co, 20996, for the file. I re-discovered it this afternoon in my box of loose Massey movements. It's a Massey 3. Small size, approx 37.5mm across the dial plate, which is also marked T+S, I assume for the frame maker. It has a broken balance pivot but is...
Hi Ethan,
The patent marking on your Tobias is almost certainly referring to the (by then) elapsed Litherland patent of 1792., but not because of any legal necessity to do so, due to the licensing agreement terms expiring with the patent. By 1815 I believe it was becoming recognised that having...
I think the style of the case, particularly the edge engraving and the small circle in the centre of the engine turning on the rear cover, point to the earlier date. Also the profile of the bezel, although this may be less of an indication. The hallmark threw me - I would have said definitely...
Hi John, thanks for filling in the info on Edward - he is much harder to research than his son ! The TF link to Vale & Rotherham is interesting, as Rotherhams is where Edward Thomas served his apprenticeship. Something pleasingly symmetrical in that :)

Hi Seth, that sounds like a feasible explanation, but I don't think an original minute wheel of a radius that allows it to fit between the "original" post hole and the bridge would engage with the teeth on the canon pinion. Taking measurements from the image is unreliable because it was taken at...
