The first 'F' types were
called '12/70 Magnas' and were only retrospectively known as 'F1s' after
the introduction of the 'F3s' that shared the mechanical improvements of the 'F2' (e.g. the 12" brakes but not the 2-seater body). Some 'F1s' may

8" brakes and either the Tourer and Salonette bodies as fitted to the 'D' type Midgets or were supplied in chassis form for special- bodies to be fitted. Quite a few
'F1s' have been rebuilt as 'F2'
