The recurve was a holdover from archtop practice- remember, the Lester's top carve is there because Gibson was tooled up to do it, something they had over Fender. On a fine acoustic archtop - an L-5, say, or a D'Angelico - the recurve area and its thinning are a key part of defining the guitar's tone and responsiveness; it's roughly the equivalent of a speaker cone's foam surround.
Nice examples!
I would like to get mine 'upcarved' which you can see is there but just not as prominate as other historics. I guess whoever was on the belt sander that day was a little lazy or under the weather but I love the finish right now...
AS the original poster of this thread, and after reading all your replies, I decided to do the Pine test (with a small 90 degree set-sqare), and lo and behold, my 95 and CC15 do have a small upcarve. I will post pics asap. So, apologies to all for my being such a doubting Thomas. Just shows that my comments about you see what you want to see (not that I did not want to see, if you see what I mean, in this particular case) is just not true. And me being an artist and all!!!
I was skeptical about this too, until I set my r6 on a level surface and placed a large steel marble along the widest part of the top. It stayed in the "valley" as I lightly nudged it around the edge. On one of my r9s though, it rolled right off immediately. So clearly not all lps have this feature but I can confirm at least one does... I intend to test my other lp's as well but they're all in their cases atm. Interesting!
