Hue's suggestion gets my vote, Dave.  After all, the ARB was intended to 
be used in tanks as well.  :-)    The Navy aircraft compliments list I 
put on my docs web page is the only one I have seen but was apparently 
assembled circa late 1942 as the ARB was just coming out, judging from 
the aircraft types.  I have no doubt that a lot of RUs were replaced by 
the ARB as time went on.
