Hi Gunner,
I have also researched the history of the Dinky, Dinky Toys, Dinky Supertoys and Super Dinky marques for the Encyclopaedia. There is plenty of evidence that he marque Dinky Toys has not been used after the take over by Airfix in 1971 until Atlas launched their copies of Dinky in France in 2008.
It is not known yet why the marque Supertoys was not used between 1951 and 1955.
In 1957, there is a change in the design of the marque which is now written in slant characters.
In 1964 the French and English catalogues show the marque with the word TOYS half the size of Dinky and the USA catalogues show DINKY only without TOYS.
1965 is the last year when the marque DINKY SUPERTOYS is used. After Lines bought Meccano Ltd. the marque Supertoys disappeared.
In 1969 the marque became DINKY® Toys, the word "Toys" been half the size than Dinky indicating that it was not part of the registered marque. The series of GMC trucks made in France are marked "SUPER DINKY Production MECCANO France" with the word SUPER in small letters until the take over by Triang when they become "DINKY TOYS Une Production MECCANO Triang" and the dies are altered to reflect this change of owner.
1972 sees a new DINKY logo which will be used until the end of the Dinky story.
The 1976 to the last U.K. catalogue published in 1978 show DINKY® DIE CAST TOYS with DINKY three times the size of the other words. This shows clearly that the marque is DINKY only.
The front cover of the1980 trade catalogue shows DINKY without any thing else and the MINI DINKY made by Zylmex are not MINI DINKY TOYS..
In 1989, the DINKY COLLECTION is launched but he word TOYS is not there.
In 2006 Mattel issues four Matchbox models made in China. Note that the card boxes are printed DINKY™ and the base plates and plastic cases DINKY® !
In their advertising, Atlas uses the marque DINKY™ TOYS with the two words of the same size
All this means that without any confusion that there have been many changes and that the marques "DINKY TOYS" and DINKY SUPERTOYS have not been been bought by either Universal or Matchbox or who ever because they were not use and probably not registered any more since 1964 and 1965 respectively.
Please also read
en.wikipedia.org/wiki/Registered_trademark_symbol about the use of the ® and ™ symboles.
I then suggest that you remove from your post the names "DINKY TOYS" and "DINKY SUPERTOYS" as there is absolutely no evidence that General Mills owned the marques DINKY TOYS and DINKY SUPERTOYS ( this is even most unlikely ). These marques could then not be sold to whoever, Universal or Matchbox. Where is the contract ?
This should not be considered as an argument against Jim, it is just a friendly discussion to try and set things right. Any body who has researched this story may have missed a fact and I always welcome informations suported by evidence.
All the best Jim.
Jacques.
