A unique and rather bizarre-looking radio cabinet design. The hole in the top right corner of the cabinet was intended for a carry strap, missing from this unit. This example has a cabinet with a dark green body and a gray back half, a gray volume knob and a gray front overlay — another example I've seen has the exact opposite color scheme.
Some very stubborn chassis mounting screws have kept me from seeing what's on the underside of the pc board — thus the ambiguous transistor & diode designations above, taken from the info on the paperboard pc board cover shown below.
Like many European MW/LW radios, this set's MW band is calibrated in meters and the LW band displays a handful of LW broadcasters by name.
Radios made in France designated their bands as "PO" (Petites ondes) and "GO" (Grandes ondes), "PO" being MW, and "GO" LW.
