Rainbow radio 750

[AdrianPH]

I appreciate that this may be going off topic But I have found some more articles in May 1952 Practical Television and also in December 1953 regarding the Rainbow TV's, The 52 one is quite interesting as it shows an internal image of the TV, you may not much detail from it however.
