I had a 1939 Murphy A92 (UK model) which used bandspread on SW. It bacame quite a popular feature in late 30's sets. It is possible to arrange the local oscillator to cover a reduced range by choosing the correct fixed/variable capacitor and inductor. Bandspread as far as I can see is a marketing term which means a narrower than normal band coverage whatever normal means. Ferguson and others were making multi-band short-wave receivers in 1937.
