Sony UK sent a van to pickup AppleVision 1710s when we had a collection that needed servicing. I suspect that Sony were heavily involved in the manufacture but I don't have the time to investigate further.
Shadow mask seems to have emerged at Mitsubishi (see http://www.google.com/patents/US4973879) but it was later used with aperture grills. ViewSonic used the tech well in the late 1990s and I recall them using Mitsubishi branding.
Apple sold a 15" shadow mask monitor in the mid 1990s that was reasonable -- not Sony quality, not a goldfish bowl. I think Hitachi were the OEM.
