Albert,
Thanks . I'm a little red-green shift colorblind. So the gray could easily appear green to me. I'm working on Shamrock V and some sources give her bottom color as charcoal gray. Your lead pot explanation could account for that. ( I can't verify that, but some examples of models of her have her bottom painted charcoal gray).
I have a copy of "America's Cup Yacht Designs1851-1987" by Francois Chevalier and Jaques Taglang, signed and numbered 1691, In French and English. It was offered on Amazon and I took the plunge for $1200 .But as soon as they confirmed the sale they promptly notified me that they'd ceased doing business with the seller in France and notified me that they'd cancelled the order, so I was never charged for it. So, assuming that this rare book had slipped through my grasp, I did my best to forget about it. Then about three weeks later a large package was dropped on my front porch with a loud thud. I was a large package( about 30 lbs.) wrapped in brown paper and wall papered in large French stamps. Apparently the seller had shipped the book, gotten paid by Amazon, who, in turn, thinking they'd cancelled the order, so informed me and never charged my credit card. So I got a book that sold at auction the last time one came on the market for about $4k, for free! (Jeff Bezos won't miss the $ I suppose, I still have the receipt).
The book is the bible on all America's Cup challengers and defenders, as well as related yachts, like Britannia, between1851 and 1987, with all the history and original lines and sail plans. No color or photos. For that, you are right, america scoop is a treasure trove of vintage photos. I found a lot on line of Britannia as well.
The book would be more useful if I took it apart to copy all the plans laying flat. But it's too valuable to do that as it is in very good condition. But unwieldy as hell.
The pages are very heavy gloss stock with very fragile hand binding. Fascinating reading, but almost unavailable in any library outside the Library of Congress and Rickover Hall at the USNA.
You certainly have added to my Knowledge of Puritan. Now I reeeeeeeeeealy want to build it. But I am afraid I have made my bed for the foreseeable future with Shamrock V, Flying Cloud, and a few more Amati J boats, and have to lie in it. Thanks so much for all the tips and info, not to speak of your interest. I am an inveterate kit basher.( See my "John W. Cannon", bashed from a Scientific Models "Robert E. Lee" kit, Gallery12, Or "Chasseur" from Model Shipways Pride II plans). Kits, like lottery tickets, only marginally improve your chances of success. If I can scan, or make a copy of anything from the book for your interest I will endeavor to do so.
I remain, a great admirer of your work,
Pete G.
