This is the Cannon Professional 6 and is on 35 MHz, which, according to Mike Kitchen, leads me to believe that it might be one of a batch sold by Nigel Wayne of Diss in the UK during the late 70's/early 80s.
It is a 6 channel Tx which uses Dunham sticks and auxiliary, with "early Kraft propo" meter and switch.
Traditional construction for the time of an Oatmeal coloured vinyl covered aluminium case.
The receiver is very small and I have put a FrSky 7 and micro servos in the photos to show how small the Cannon servos were at the time.
