That's an unusual one. I've seen exactly one Hitachi SW, and that was
a small portable at the original EEB store in the early 1980's.

He has some interesting receivers that I've never seen but would love
to own. The RF1010, and FR6600 look interesting, but are probably
impossible to find outside of Japan.

The website owner does have a rare copy of the small table version of
the R-300. It was a little known model that was compressed especially
for for apartment owners.
