Thank you ThomasI think it is a version of the British or Canadian made Wireless Set No.19. It was a fairly common radio set used in Commonwealth tanks and military vehicles during WWII through the early-1960s(?). The Commonwealth forces also used it in FAC/Army Cooperation aircraft. It was provided to the Soviets in significant numbers as part of the aide (Lend-Lease?) in WWII.
Thank you for this detailed answer. The enigma has been solved.Yep .. that's the Wireless Set No. 19 that was a Second World War mobile radio transceiver designed for use by armoured troops of the British Army. First introduced in 1940, the No. 19 began to replace the pre-war Wireless Set No. 11. Two modified versions were introduced, Mk. II in 1941 and Mk. III in 1942. An improved version from Canada was introduced in 1942 for use primarily with other forces. In British service, the No. 19 was replaced in the post-war era by the Larkspur radio system. Canadian-built No. 19s saw continued service for many years with a variety of users. Very popular among radio amatours. Judging by a couple of the contemporary changings introduced it may be one of such devices. It seems to be the Mark II orginally. However there is a lack of the data plate at the bottom of the panel. The dual English/Russian legends on the front panel indicate a set produced for the "Lend-lease" program. Possible never sent to Russia.
