Mark and Doc: Thanks for taking the time to comment.
Pete: Thanks for the kind words. On a side note: These guys were driving, as Ronald once said, "with no regard for the old material". I think one would want to confirm the Bentley's recent service history before considering it...
Azzo: Thanks for the generous compliment.
BTW, Stuart, this was taken with a modified "DR" Summicron, and a Leica digital camera that shall remain unamed here... lest the flames reach this thread
Cheers all, David.
P.S. Here's an expanded view of the same curve, about one half hour later... nice view, eh? (This must be the 28 Elmarit ASPH)
