Thanks for the reply Philippe. This was 20-25 years ago as my father was there, and the Toledo Toy Show was the second best place on the planet to consistently find good vintage large scale slot car stuff! At the time I was really more interested in 1/32, and, was finding so much stuff I thought I could always find more! As you say, most likely someone got a case of Porsche Super Spyders and had a couple new ISO bodies and pulled a switcheroo. Second most likely the factory or a distributor in the last days pulled the switcheroo during the clear-out. Third most likely that the factory actually did it in the final days and now we wait for the worlds only remaining Russkit Super Spyder Iso Griffo box to be found!
