It is a Matchbox copy by one of the Japanese copiers... AHI is the most well known company but there are others. It is probably an antimony/lead/tin based metal which is why it feels lighter.
It looks a lot like one by this
Japanese company who use packaging similar to the AHI packaging. A history of AHI can be found at
http://toysnz.com/AHI-Japan. I'm pretty certain this is NOT by AHI as it is a much cruder casting than the AHI castings I have. Of course I'm always open to being corrected by someone who can add more information on these wonderful (and not so wonderful) copies.

G'day Ian,
Great to hear from you and your input into this Copy.
If the picture Ghosty has posted is the AHI (wheels inside) model I would say you are correct and not AHI as mine has wheels outside.
Interesting about the Lead/tin metal, it is the only one I have.
Cheers Al.
