The mini I was shown was a 2.5 inch Skyla from
this series.
It would appear that though they were manufactured by LJN, in England they were marketed under the Matchbox brand. Take a look at
this eBay auction to get an idea of the packaging.
The player tells me he has three more of these, each in its original packaging, but I'm still waiting to hear which ones they are.
Thanks for the interest.
