Could this be the elusive ER-88?

The only discription I have of the ER-88 receiver comes from  a statement of capabilities sent to the Soviet government in late 1944 or early 1945. It was part of an attempt to reactivate the 1935 technology-transfer deal under which RCA built a TV transmitter for Moscow, etc. READ IT HERE

It describes an AR-88 receiver with a 10-watt audio output, likely using push-pull beam power tubes.  These pictures come from Brian Goldsmith.  It doesn't look to me like a factory job.  Please share your thoughts. - Al - N3FRQ
