Late to the party, sorry about that. Wasn't paying proper attention.
I have been looking at a few Dutch market catalogues, and the 'Flying Dutchman' model name was used during the seventies, and was still in 1979 price list. It had disappeared 1983, wasn't available in 1985 and was back again in 1988.
The 1988 version had drum brakes, a Sachs 3-speed hub and only came with 26" wheels for the ladies, by the look of it:

So my best guess for now is that it is either just pre-'83 of just post-'85.
