- "Early radio equipment from the 1930s - can you ID?"

The two receivers behind the mic, and atop the power supply and coil 
rack are very likely National Company RHM's.  These were designed for 
the Lighthouse Service, and were the predecessor to the more familiar 
National AGS.  I don't recognize anything else.
