With excellent provenance, this is Matchbox Superfast no. 38, Soopa Coopa. Model has never, ever been played with; one owner only (me), thus Mint. Box is Near Mint, with the most microscopic dink to one corner and a very tiny tuck flap tear (see photographs)
I have many, many more of these coming up for listing; I hand on heart don't think I've any of the real holy grails, but there's a few of the nicer ones and every model I have is mint, with most boxes M or NM and a regretful few missing flaps.
Please get in touch if there's anything partic outstanding for you.
All models will be shipped Royal Mail signed-for in proper boxes.
