Hi Watchrepairtalk, I have some questions about part sourcing I was hoping someone here might be able to help with.

I'm working on an FHF 180 movement with a broken balance staff, broken regulator pins, and damaged cap jewels (both top and bottom). Some Googling says that this is similar to other FHF calibers like 150s, 160s, 180s and so on but I can't figure out what the functional difference is between these movements. 

Is there any reason I wouldn't be able to acquire a donor FHF 150 or similar (with no shock protection) and use parts from that or would it be smarter to source replacements individually? Also are there any sources someone could recommend to get bulk cap jewels like this? Thank you for the help!

Why do you think this is Fontainemelon ? 

The balance staff you will need to source separately.  But first it's important to accurately identify what you have there. Research Ebauches Sa, see who was in group, to find the brand that made this movement.
