[ARC5] Right angle drives

[Michael Hanz]

 From the early 1930s there were only two sizes, Hue.  Large and (later 
on) smaller.  See https://aafradio.org/garajmahal/flex_drive_cables.html 
for the dimensions and a lot more.

Everything _except_ the ARC produced gear used the large one, including 
the ARB and RU receivers.  The confusion is usually over the Army and 
Navy terms for them (MC-*** versus the more complex Navy numbering 
system), compounded by often nothing but manufacturer numbers like your 
S. S. White example.  The "large" design even had a square drive, which 
I mentioned on the web page above.
