Pallet fork was in. I’d had the movement running ok, and only removed the balance to flip it over and install the keyless works and date mechanism. The pallet fork wasn’t locking the gear train when hand setting - it was oscillating as the escape wheel rotated. This may have been in one direction only - can’t remember. -

Hello and welcome to the forum Dan. Used to know Middlesboro quite well, that was twenty years plus ago. Attached a little reading to get you started. TZIllustratedGlossary.pdf -
for the most part no. Each individual watchmaker and/or shop had their own system. One of the shops I worked at basically had a reference to a page number in a book. then there are some shops that do no markings at all as they keep their records on a computer and they don't have to mark the watch. Usually if somebody is marking and they've service the watch before you'll see those next to each other. then as far as anything resembling a standard goes at one time the American watch and clockmakers Institute assigned all of their members a number. but that was a very long time ago and I doubt that they are using it anymore. -

I don't think the 916 would fit, another problem is JL parts are restricted. Only other option is to measure the stem and get a generic replacement.
