Philips P99 manufacturing date

[compuvac]

I recently acquired a Philips P99 and want to find out what year approximately the P99 was manufactured.

There are no date stamps anywhere on the plastics last time i checked.

I would appreciate if someone could tell me what year it was released/discontinued or what time period it was sold as I have no idea but i assume it's somewhere from the late 80's early 90's

I think Mike from Finland might know a thing or two about Philips.
