Here in Britain mechanical rotary tuners mostly went out in the late 1960's/early 70's when new TV's were UHF only & had push button tuners, the exceptions were the early Sony KV 1300's & 1800's that had rotary UHF tuners, also some cheap black & white portables had rotary UHF as well... Up until 1955 all TV in Britain was on 5 low band channels & many sets were fixed tuned to one channel, when ITV fired up in 1955 new TV's would have rotary tuners with 5 low band channels (1 to 5) & 8 high band channels. (6 to 13) Some TV's had the channels on the tuner out of sequence, we had a TV were channel 4 (BBC) was next to channel 8, (ITV) on the other side of 8 was 5, also 1 & 9 was next to each other, this was for viewers in London & Belfast where BBC was on channel 1 & ITV on channel 9. The set makers did this so you only had to click once to change from BBC to ITV as they were the only 2 channels you could get back then...
