Notes
hunter calibre
options: bimetallic screw balance, Breguet hairspring
There are various bridge layouts, two base plates with differing dial-feet positions, and two slightly differing setting-lever springs.
The assignment of such differences to the groups FHF 1 to 14 and the calibres FHF 1144, 2144, 2146, 4144, 4146 is just partially known. But comparing the according calibres gives an imagination.
FHF 1 to FHF 16 designate movement groups containing calibres of different dimensions; individual designations start with FHF 22.
