It seems that these monitors (or at least their picture tubes) were manufactured in Ichinomiya in Aichi Prefecture, Japan. Apparently mine was manufactured in 1996.
Mine had a few defects when I got it (missing Sony logo, kind of grubby, dumb calibration settings, base has been hacked apart for some reason - perhaps to fit into some rack mount?), but was overall a pretty good deal at $50, free delivery!
