Fontainemelon, but which one?

[BlueHarp]

Hello,

I got an old Unic watch in bad repair, but which is far better now, although the crystal is missing. The movement is engraved with the logo MHF (Fontainemelon) and with the indication Unic. I have found 2 calibers very close to it on 17jewels.info (1144 and 1156), but I'm not sure this is one of them. Could anyone help? I understand that this movement could be 100 years old ...???

Is the MHF a typo?

What size is it and do you have a photo showing the keyless works?

FHF 1146 looks pretty close as well

The logo Fontainemelon appears as the to letters FF opposed to each other, and the diameter is 21mm. I understand that means 9'''1/4.

This is Fabrique d'Horolgerie Fontainemelon logo, one of the three founding companies of Ebauches Sa in their shield. Unmount the movement from the dial and you should discover the caliber number.

Is this the Logo which if FHF not MHF. I expect it's actually 22mm as 9 3/4"

Here are 2 picures I took while disassembling the movement. As the previous one shows, there is an additional engraving ("Unic") that was also on the dial, so I guess this is the watch manufacturer. Maybe he modified the caliber?
