[R-390] Unknown R-390 model

Hi, I have asked this question a couple of years ago, but since I 
suffer from CRS, I don't remember the results.....


About 5 years ago, I ran across a guy who bid on the contents of a 
storage building. He had NO chance to preview what was in there.

It had a couple of these receivers. I bought one for almost nothing, 
thinking it would be a good source of parts.

The radio appears to be a R-390A with extra 'boxes' on the back. I have 
the metal tag that states... "R-1891".

A couple of years ago, I searched the WWW from work with no results. 
Now that I'm retired (and the WWW is much more 'full'), I have

tried searching again. I still cannot come up with an answer. What the 
heck is this variant???


thanks!
