I found what appears to be a Welly Porsche 930, but it’s sealed in a bag. Were these ever cereal promotions, or giveaways somewhere?

No silver on the right side wheels...

Left side has one sloppily silvered wheel in front, and something’s rusting back where the power is made.

No help on the base, besides the Made In China text. Although, if you look closely, you can see that this is one of the rare 911 derivations that had a big honkin’ engine in the front. Complete with driveshaft and exhaust pipes.
