can't believe we two dinosaurs are still up doing the research! 
i just checked my Mcquillan (ball in hand) Piedmont 350 and the clouds
are clearly delineated and vibrantly white---like the one you suggest looking
at on ebay.
it's very reminiscent of the ritchey discussion---
sure continues to clarify the 150-350 progression issue.
whatcha think, brian?
going to bed. but will be back doing the research in the morning!
best,
barry
