[Milsurplus] Boehme Keyers

[Robert Flory]

Hi,
I am trying to figure out what model(s) of Boehme keyer(s) was used in the
Navy Radioman schools in WWII, as referred to by a vet I have been
corresponding with.  Searching on the net, I have found a high-speed
punched-tape model that doesn't go slowly enough for code practice, and
inked-tape types used by the Army.  A perusal of Ships 242a did not come up
with Boehme as a Naval contractor, but did come up with several equipments
put out by Navy Yards.  Maybe they had the Boehme keyer as a component.

Anyone have such a beast with Navy nomenclature on it, a picture of said
gear, or other info that might help me in this quest?
