That's brilliant! What a great set of books they are! Thanks for that. Another quick question. I've noticed on the second picture of the movement on the data sheet there is some sort of spring held down with a screw towards the bottom left. However in the fourth pic the spring isn't there. My movement doesn't have that spring or screw. Are those pics fully assembled and just different types or is it missing?

Those movements are submitted by anyone as far as i know, folk that helped to build the database for Ranfft.  Those 4 pictures show 2 different variations or possibly families of caliber. Notice the two different bridges. But the set and wind are the same design, the spring is the click spring, these are common on oris movements. So that spring and screw on the last picture is missing as i think so is yours sorry.

the spring is the click spring

I'm confused, I  can see the click in the usual position next to the ratchet wheel. Surely the click spring is there?

You're  right Rich on the op's first picture there does appear to be a spring popping out under the ratchet wheel, wonder why its not on the dial side ?

Just noticed the remarks on that screen shot you sent @Neverenoughwatches  it says ratchet on back side, crown wheel just for show. So I think the click can be in 2 different places?

Maybe so, there looks like a piece of spring under your ratchet wheel.

Yeah there is a spring under there. Hopefully now I can source a screw for the click and the bridges! Thanks for your help!
