The color of this cabinet really is as shown, a beautiful pale green. The black plastic raised-lettering "Koliber 2" logo and the black dial center and dial numbers create a striking contrast against the soft green background of the cabinet body. The Koliber 2 came in a number of other cabinet colors, yet I can't help but wonder if this green cabinet with its black trim was intended to mimic the beautiful green-painted TEWA transistors with their black lettering found inside the radio (see bottom photo below). Stamped on the lower left corner of the cabinet's back face are the English-language words, "MADE IN POLAND", indicating that this radio was made for export.
The five transistors here consist of a pair of COSEM France black can SFT319s, a pair of TEWA Poland green painted TG50 top hats, and one unmarked TEWA green "Euro"-shaped audio transistor.
TEWA was Poland's semiconductor manufacturer — it didn't begin producing transistors until 1960 (AF transistors), so the Koliber 2 may have been the first Polish transistor radio to routinely employ Polish-made transistors. The 1959 Eltra MOT-59 and the 1960/61 Koliber MOT-601 both appear to have used transistors produced by Western European manufacturers, although some units of the 1960/61 Koliber MOT-601 may have incorporated several TEWA audio transistors.
