Linkert M88S 1946-1947 MILITARY? CIVILIAN?

The M88S does not show up on any production H-D motorcycles.  However, it is in the Linkert Company's blueprints, as produced for Harley-Davidson and for the 45's. It shows a short choke shaft lever, which the military used for their air connector for the oil-bath air cleaner?  Not a longer chole lever for the civilian style air cleaner. And it did not have a set high speed needle but an adjustable one, again like a civilian model. Was it produced for a foreign civilian or military like the M77?  Regardless, it is painted and restored per the Linkert Company blue prints.
