A mystery West End Watch -- What the movement is?

[Jonnes]

No any markings......

It must be a FHF movement but I can't figure out the exact calibre number......

The balance staff and screw for setting lever are broken

the screw

The shape of the keyless does look like an FHF. What size is the movement?

Is there any writing under the balance?

Looks like an FHF 30 or 32

Edit

Bridges don't look right though?

 Apart from Depollier shock spring , I agree,  its based on FHF.

I think's based on an FHF 30 and the bridges have been changed by West End.
