As soon as you pick one up you'll know if it's magnesium as they are much lighter.

Nice wheels.

not always true, the 1960's magnesium wheel Mark has is heavier then both a modern 6x10 genuine minilight and the k&n minator type!

The ones I had were probably so light as they had rotted away!

Genuine magnesium wheels will be siginificantly lighter than equivalent aluminium ones. The density of Al is 2.7 gms/cc and of Mg is 1.74 gms/cc.
Magnesium corrodes much faster than aluminium because it is more reactive and does not form nice stable oxide films. Magnesium is actually used to preferentially corrode when in contact with iron (or steel), so on Minis it will corrode badly around the wheel studs for example.
Hope this helps.

You can't have too many cars. Just too little space...
