I am trying to locate a wrist brace as worn by Michael Jackson in the
Black or White video and on tour.

There are some good pictures here:

It appears to be a very long surgical/orthopaedic wrist brace made
from white canvas.

The closest I have found so far is '781 - White' at:

but this is not long enough. MJ's brace nearly reaches his elbow
which, on a 6ft man, must be 11-12 inches long from palm to end.
(search strategy below)

Please could you locate me a wrist brace as close as possible to MJ's
in white canvas (or v. similar), no neoprene, no plastic.

Extra points (and tip potential!) available for an exact match and
being on sale in the UK (though not critical). Have lots of other MJ
costume questions so there's plenty more there if this is successful!
