Whyte prst1 works special parts

[rod998]

I've just bought a great example of a Prst1 works special...However she is missing some of the original works special kit...

XTR M952 3x9,
Hope 4 pot brakes,
Hope XC hubs on Mavic 517 rims,
Easton carbon seat post and handle bar
Middleburn crank

Any help in sourcing any of these parts or near enough would be greatly appreciated!
Thanks
