Discussed many times here on the forum.

I can't remember exactly, but think it indicated centre pinion height.

I thought so to. But didn't know what to search for. I will check.

Yep longer thingy the hands go on so they reach over higher markers ( like onyx inserts )

“Thingy”, often defined as centre wheel arbor, cannon pinion, and hour wheel. 😀

This number denotes the "hand height" of the movement. This in turn tells you how long (tall) the hour wheel, cannon pinion, and sweep seconds pinion will be. Center wheel stays the same...
