Seem to be Varitronix (found them listed on some werd Russian overstock=20
site).

If I had a lot (>100) I would remove the black gunk to take a look at=20
the controller chip and the on-glass wiring. From the NxM (assuming it=20
is graphic..) and the shape of the chip you can do a guess and see=20
whether the chip matches (in the old days there were not *that* many I2C=20
or SPI COG LCD controllers. Philips, now NXP, would be a first guess).=20
That gives you the pinout, but often you will need some crucial=20
initialization settings that might be specific for the LCD and=20
impossible to determine.
