Looks like a Bush VHF61. Details of the set can be found in the 1957/58 Radio and Television servicing book. VHF61 is housed in a Bakelite cabinet and VHF62 has a cabinet made of wood.
Excellent performers all helped by having two IF amplifier stages on AM and three on FM, the ECH81 heptode section serves as the additional IF amplifier on FM. Valves: ECC85, ECH81, two EF89, EABC80 and EL84 output. EZ80 rectifier.
Intro date, late 1956.
A year later Bush introduced the models VHF71 and VHF72. Not as good as the VHF61/2 because these sets have only one IF amplifier stage and employ Mullard U series valves.
