How old is my Grundfos pump?

[doitmyself]

I have a Grundfos Selectric 15-50, which looks similar to the current version but with one significant difference: the speed control knob is white and the numbers are on the flange of the knob and appear in a slot cut in the black surrounding. The only numbers I can see are:983484 and U327, neither of them appear in the Grundfos Webcaps database.

The versions with black speed control, with 1, 2 or three dashes to indicate the speed, were around from 1997, so it must be older than that.

Any ideas how old it might be?
