....They aren't magnesium.....The original racing slot mags were a magnesium and aluminium alloy, but this wasn't robust enough for a road wheel so various manufacturers who made this design of wheel (known as a slot mag) made them from aluminium. Yours on the TVR are aluminium, hence needing lots of polishing.
Thanks for the clarification. The car was bought by a chap in Germany in the mid-1990s, and (sadly) I have no idea what became of it after that. A splendid car, one of those "I should have kept"
