HRO; "much modified" see below

The HRO was available in large numbers after WWII and was used as the basis for pepping-up using modern valves by many radio amateurs. The awkward tuning arrangement wasn't important when looking over an amateur band. All you needed to know was the band edge settings on the dial. Actual frequency was relatively unimportant. The resetting accuracy using the dial's vernier reading was very useful.

The design of the HRO must have been good as both the Japanese and the Germans copied it during WWII.
