  • Model R-28 of the R-28 series. Advertised as Model 28 or R-28, there are two versions of this radio, one with Police band (R-28-P) and one without (this model).

    The models of this series have a sticker in the cabinet for Model R-28, plus a sticker on the chassis Model R-28 or Model R-28-P.

    In advertising and folders, the models were further divided, e.g. Model R-28F for the Duncan Phyfe table etc. There suffixes however do not appear on the actual radio - as far as we know.
