Can anyone id this RC car?

I picked this up at Beaulie Spring Autojumble on Sunday but I am not sure who makes it. It has a few spares packets with it that say Mainstream Scorcher but a Google search just brings nothing relevant.

Gives you a 1971 date, and the chance of finding the magazine at least?
