Which Barry?

Gene -- I assume you have a bad motor?  What's wrong with it?

There are rumors of motor mechanics hither and yon who can rebuild these
things.  If I'm not mistaken, one of mine is made by Hamilton Beach.  It may
well be an adaptation of something more generic, like a MixMaster or other
appliance motor converted made for 24-28vdc.  Maybe some kind of 24v truck
wiper motor?  The trouble is that its design is from the late 40's/early
50's.

The R-105(a)/ARR-15's have a similar motor, but I think it's smaller and
less powerful.  Some tuning modules for the APR-4Y (four band 20 Mhz to 1
Ghz) have a "scanner" motor, but I don't recall the voltage.  The receivers
were originally AC/400 cycle, but I don't remember whether there was a
separate DC feed for the motor or if it was AC.

It's possible your existing motor may be rebuildable.  Many old ones have to
be rebuilt anyway -- new brushes, commutators turned down and back cut,
bearings, etc.
