Just seen the empty box for one in Control's flat in the new film of Tinker Tailor Soldier Spy . I have one but I did not think they were around in the mid seventies when the film is set. I think it undermined the cedibility of the whole film.
For goodness sake don't watch any more 'period' movies then! The film spans late 1973 into 1974 and the CS-505 was around from 1978 I think. However, Dual had made previous - and very similar - turntables at least as far back as the relevant period.
I saw an A&R Cambridge A60/T21 combo (black veneer) in a record shop in 'Life On Mars' (set in 1973 and a few years too early for A60s.)
I saw a Revox B77 in 'Bank Job' which was - again - a few years too early and should have been an A77. (Actually the real 'radio ham' used a cheap cassette recorder to tape the bank robber's walkie talkie dialogue.)
'West Wing' is full of inaccuracies (one occurs in the opening moments of the very first episode) but I love the series anyway.
Pick a period film (any) and some 'expert' (on cars, audio, fashions, art, retail, road furniture, accents, mannerisms...etc.) will find mistakes.
Unless the errors are gross (Nokia ringtone faintly heard in a mediaeval banquet scene) then I don't really worry too much.
