Kevin,
Can I respectfully suggest that you be more discriminatory with your reference material.
Who knows what that machine has been through over the years!
In fact the originator of those actual images (desmo57) stated on this forum that, that bike was heavily rebuilt.
The images that are most trustworthy, are the ones taken when the bikes were new, hence the importance of 'period magazines' and pitlane/raceday photography that can be traced to a particular event.
On the subject of the difference in profile of the nosecones, you are correct.
I have images of only 1 RRR that had this lower screen nosecone from new (Motorad-magazin July 1991, Track test of Bernd Caspers new 91 RRR), most often it 1992 racebikes that have it. My bikes nosecone, the original it was built with, is around 25mm or so higher than my NOS one. My NOS one came from Mark Forsyth along with other spare parts when I bought the bike.
The nosecone's in the attached images show the difference, I think, you are referring to, though that is the only reason I post them, to illustrate that there is a difference, I know nothing of the history of the Barber museum bike.
