What would you like to know about them?  The R-11 covered 190-550 KC and was
essentially an updated R-23A/ARC-5 sans BFO and dial.  (Okay, nitpickers, I
know there are details I'm skipping but this is a thumbnail sketch!)  The
R-22 was like the R-10, a Type-12 version of the R-24/ARC-5 covering
.520-1500 KC.  R-11s are fairly common much like the SCR-274-N BC-453 and
R-23(A)/ARC-5 while the R-10 & R-22 are somewhat less common but still are
well outside the "rare" level.  All of them were navigation receivers with
the R-11 also being used for comm when towers still transmitted on LF/MF
frequencies.  

I can send you the pinouts if you like.

Oh, yeah.  The red ARC emblem was common throughout their pre-Cessna period
with it becoming blue later after they started making the 300 and later
series units.  I'm not entirely sure when the changeover took place.
