Ur-quattro wheels

[Philip Ross <rossp@blythswood.org.uk>]

Some of the picture of Ur-quattros around 1986/7 show them with wheels 
which differ from the standard Ronal 16 spoke alloys.  These wheels, which 
were I suppose an option, were more spoked and similar to BMW cross-spoke 
alloys.  They also appear on some V8s I think.  Does anybody know what kind 
they are?  Are they BBS and are they the same size as the Ronals?

(For anyone who gets VW Audi Car they appear on a quattro pictured in an 
insurance advert on the back cover.)
