A pre war Hallicrafters, and an early one too, very nice! 1936 is pretty early for metal tubes too, which would explain why they used a 5Z4, I've mostly seen those in Canadian Westinghouse sets from that period, 1936-37, later ones used a 5Y4. Canadian Westinghouse owned their own tube factory so they went all in for metal tubes in many sets, I have another with a single ended 6L6, not G or GL, a metal one.
