Manufactured by Sheffield Radio Ltd in about 1958.

5-band bandspread unit by Sheffield.  Year is a guess based on the model number and ARTS&P label, although the set appears to be of early 40's design.  Interesting mix of glass, metal and loctal valves - also appearing to be an odd mix of 30's and 40's technology.

Valves (6 + eye) - Lineup not currently known
