Guess I'm a bit puzzled. None of these mid '60s beauties look anything like what I've always considered to be the F-30's "mini-jumbo" shape version - which I believe first appeared in late '72, and for sure in '73 with both the F-30 & F-30R. These are clearly distinguished by a very round bottom (measuring 15-3/8" on my '73 F-30R) and deep lower bout (4-7/8"), combined with a much smaller upper bout (a hair over 11") - truly mimicking the miniaturized shape of a jumbo Guild or Gibson.
The two '60s examples above appear to have some very slight differences in curvature, but both more closely resemble a Martin 000 shape - and I'm guessing their body measurements would be virtually identical.
Imho, it seems like a misnomer to be calling one of them a mini-jumbo shape. That said, I believe the world will keep turning!
You're right Bobouz, the "mini-jumbo" F30 I've always known is the early 70's model... I thought that the F30 had gone from the Hoboken OM body style to the Westerly Mini-Jumbo at that time. That's why MJ's 66 has got me puzzled. Its kind of a mix between both versions...
The best of both worlds!
