  The black banded Madison Moore RF transformers were first advertised in September 1926, a little more than a year after the MM superhet was introduced. The first MMs used 199-style tubes, but the black banded IFs were used with 201As exclusively. The markings of "HW..." indicated the new transformer frequency for their "One Spot" IFs, running at 92 KC up from 35 KC.
