This machine belonged to a friend in the UK who ran Savoy Hill Publications (an excellent source
of vintage hi-fi and audio service manuals).
He had a radio business in Bristol for 25 years and used to travel the countryside, occasionally buying up used audio equipment.
This recorder was bought in the town of Worhing (and used for on-site recording) from an ex-employee of a film company – the recorder was used in Cliff Richard’s (Sir Cliff!) first film “Expresso Bongo” circa 1959. ( A MUST see film, a classic insight into pre-Beatles British pop music!)
