Balance staff equivalents

[p2n]

Is there resource that lists alternative designations for things like balance staffs?

 

I need a U936 (according to Ranfft) but I can't find one listed anywhere.

What movement is it for?

Also is it shock proof or not, because that can depend on the type you need.

From the Zentra I've been fiddling with - believe the mech is:

Sorry, I am unable to track down a replacement. You might have to make one or have one made. Some kind member on this board might be able to help you.

It's ironic that of all the movements I have I've managed to identify one and find the parts are not available lol.

Last night I was wondering if I need to learn how to make them - it would solve a lot of problems.

Vacheron has some 16" balance staffs for Parrenin on Ebay.

I have a balance that says H.P 16" . When i googled parrenin the name H.P came up . It has a brequet coil. As well as some 40 and 60 parts. That also says H.P on them . So think it could be right.

I know this is probably obvious - but how do I identify the calibre? This seems to be one of those things that's so simple and obvious to watchmakers they don't define it and it's a mystery to me lol.

Only think there are two different  H. Parrenin in 16 ligne. They are different height so check which height your movement is.

The movement is 4.15mm thick and 41.1 dia
