Brief Description: Receiver Type R1155A, in black crinkle-finish aluminium case, with filters fitted to prevent interference from MF transmitters (hence designation model A). Receiver includes older style bakelite? tuning dial with perspex? half-moon multiscale display. Tuning dial is different to that of post-R1155A models as tests revealed the original dial was difficult to tune at high altitudes due to the operators' gloves. Other dials and knobs include those for meter balance, filter, meter amplitude, het. adj., tuning indicator, meter deflection (LOW, HIGH), aural sense (L to R), switch speed, balance (0, AVC, BALANCE, VISUAL, INFINITY), het, volume and wavelength?
