I had seen that russian page, but somehow did not connect that part number to the manufacturer. Since original items were PSU's, and display's viewable size is quite small - 49x19mm - it could be just a numeric display with 3 or 4 digits, which seem to be most popular kind of varitronix displays. Might be some kind of special order too.
