Yes and no, according to who? I have sets like that (Levin and Schaublin) but also very complete Boley sets that don't have that many. Here for example is a ww83 which is the large boxed offering for one of their top of the line models. i.e. they're weren't holding back on this one. Its complete boxed set as Boley sold it, as best I can tell, but that doesn't there aren't other things in the catalogue not part of the set. It would be nice to have an old Boley catalogue to see exactly what else they offered, never come across one
. I've also got a boxed Boley Geneva style that has similar complement of collets....none are missing but there aren't 50.
The Levin set is by 0.1mm starting at 0.1 mm. The Boley set starts at 0.5mm, has a few of the smallest sizes with 0.1mm increments, that changes to 0.2 mm. I think Boley knew a thing or two about keeping watchmakers happy and that's how they equipped one of their top of the line packages..... I mean is there practical use for collets below 20 thou? The pivot on a balance staff can be 0.1mm diameter, but you aren't holding the staff by it.
A kit like that does qualify a bit as collecting. I'd guess 99% of watchmakers did not have sets like this, probably 95% did not have a slide rest. I've bought a few estates of pro watch makers who's lathe kits were quite modest, imo all the fancy stuff is nice but not crucial for the actual business of watch repairing.
Outside of whats in the box, there is also a vertical slide, milling spindle, miniature steady rest, dividing head and thread cutting rig with tumbler and change gears. I used that the other day to chase some 40 tpi threads on a small model part that were damaged so its not just collecting. It was a kijiji find for small dollars.....one of my better deals lol.
