Mick - not any of this set; didn't know they existed until they surfaced in an online auction. I collect them unbuilt, probably have 125~150 different in current collection
In seemingly a different lifetime

yes, I did assemble one of the Nabisco models (the Jaguar, from memory).
And they may be directed at kids, but getting the folds correctly requires a kid that has built a lot of plastic (or when I was that age, wood) models.
My first wooden airplane model was a disaster
