DEFIANT A55 1961-ca.1965

And the name? There used to be a thing in the UK called 'resale price maintenance'. That meant that retailers couldn't offer discounts. The 'co-op' (Royal Arsenal Co-Operative Society, or RACS) had a system of offering dividend stamps which qualified as a 'discount'. The radio manufacturers didn't like this, and refused to sell their radios, etc. through the Co-Op's chain of shops. So the Co-Op decided it would sell its own sets (hence 'Defiant'). Resale Price Maintenance was abolished for most things in 1964 and so 'Defiant' lost its raison d'etre.
