The TRF receiver H2L/7 is in fact a design and product of NSF.
The original NSF documentation (bad copy) in my possesion is dated 1935 and 1936.
It has 1 hf-stage and 2 audio-stages.
It is a variant of the HL/7 receiver, that has 1 hf-stage and 1 audio-stage.
The HL/7 receiver is described in "Technische handleiding voor adspriant radiotelegrafisten" part 3, 8th edition, about 1934.
