I posted the other day that I purchased my first lot of Fun Ho die cast, a brand which is out of business but it used to be a New Zealand icon at the time. I finally got them in the mail today. The inspiration for these is obvious to me, you can call it a rip off if you like. Greyhound and Merryweather were their names in the Matchbox regular wheels range. Anyway, here is a link: http://history.funho.com/zinc-num.htm and here are better pictures of what they are.
