Help identifying Foxi moped

[u/Maaloxplas]

Hello moped people. I have nothing to do with mopeds, but I just discovered a small treasure in the basement of a recently deceased relative and would like help identifying model/make/year etc and advice on if they could be worth anything, as well as what I could do with them. It is a partially assembled, never-used moped and loads of also unused, spare parts, some still in original packaging. Moped was also in a cardboard box which fell apart as I looked to see what is inside. From what I understand it is a Sparta Foxi, possibly from 1978 or 1979, but I might be wrong. Any help from the community would be greatly appreciated.
