[Test-Equipment] Meg Ohm Meter

[WA5CAB at cs.com]

A lot of test equipment during WW-II never had military nomenclature 
assigned, although there was far more of that at the beginning of the war than at the 
end.  If the Megger was made for the Navy in early 1944 and had nomenclature 
assigned, it most likely would have been from the Navy system and not the JAN 
system.
