>From Ron Kitching's "Everything Cycling":-
"A top quality de luxe rim for racing in the toughest conditions, and used
by pro. teams. Extra hardness through deep anodisation. 20mm wide double
eyelets 395 gm. 36 hole only, price £114.45" (GP4s were £30.94 per pair) I think the
blue anodisation was the extra cost.
