The identification for this radio is found on
the dial. In the center it shows the text "R.R. RADIO" and
in the lower right corner the word "STANDARD".
In a Belgian magazine on historical radio the origin of the name is
explained. "R.R." refers to Mr. Roy and Mr. Revol who cooperated in
the development of radio equipment in Belgium since the beginning of
the early twenties.
An advertisement in their 1936 cataloque is indicating the model number
650. The original price of this radio was 1.295 Belgian Francs.
The first digit of R.R. model numbers refer to the
year of origin (1936). The second digit relates
to the number of tubes used (including the rectifier tube).
According to the official catalog of the 10th Radio Exhibition ("Salon
de la T.S.F.") in Brussels in 1938, the company R.R. Radio, S.A.
(address 44-46, rue de Goujons, Brussels) is one of the exhibitors.
This company is still doing business from the same address in 1949, as
can be seen in the catalog of the 13th "Salon de le Radio" in Brussels.

This R.R. Radio employs 5 tubes (2A5, 2A7, 2B7, 58 and 80), covers
two bands and the wooden cabinet measures (hxwxd) 42x38x28 cm.
The chassis has a military-like green colour.
I am very much interested in more information about this radio
The radio (acquired on a radio flea market) had the following
1. volume potentiometer burnt out (so I don't know its value)
2. two open-circuit windings in an RF transformer.
Restored chassis. The tubes are not yet put back on place and the
volume control is still missing.
