bingo. That's the info I wanted. I seem to recall also that Schwinn had some bikes with New Departure manual 2 speed hubs, I've never had a complete working unit but back when I was hoarding S-2 wheels, a few had that hub. Did Schwinn offer these post WWII or was New Departure history by 1946? I've had English coaster brakes with "Schwinn approved" anchor arms, likely Perry or Sturmey-Archer made, and of course the Komet made German ones (I like those). I was told that Bendix was jerking Frank Schwinn around a bit, so they ordered those for a few years to bring Bendix back begging for the contract.
What was the connection between Mattatuck and New Departure? I remember servicing both back in the day and the guts were very similar, also the Japanese brand N&K. I'm guessing N&K were just patent infringement copies of Mattatuck and/or New Departure.
Mattatuck, like New Departure was an American company, (I believe) but for inexpensive auto parts store bikes the N&K hub was used.
