I'am a pure matchbox collector, but that's a very interesting thread, too.
It's always fascinating, seeing great toy manufacturers being copied by a lot of other firms.
When I saw your Ford D Series, misterpop, I remember two (similar) toy lorries, which I always take to the beach in vacation in Denmark, when I was a little boy!
Could you post a closeup of the hubs/ wheels? would be interesting to know if it's the same manufacterer. They must be somewhere in our garage

Thank you all for this excellent thread.
I wish you a merry christmas.
Greetings,
Linus
