I recently found a great web site at Matchbox Kits
I cut my model making 'teeth' on these classic old kits. I used to have a collection of well over 100 of them, now I only have 1 left, my Handley Page Heyford.
Aah, those were the days! Multi coloured sprues, so you didn't need to paint them, all sorts of different genres, from Aircraft to boats and cars to motorbikes, and military vehicles and figures as well!
If you remember the old Matchbox model kits, this site is well worth a visit!
