Tacoma produced maple and rosewood F-47's, and I think West Hartford continued them, yes?
Don't know about Corona....
Connecting the dots between price lists posted on Westerlyguildguitars.com and other known history, I think they lasted at least until '83 or '84, when Gruhn was approached to design 4 new models, 2 dreads and 2 F bodies, which begat the F44 and F46 seen on the '86 list.
On 87 list we see the introduction of the "GF" 's, all of which have the definitive 16" lower bout that makes me think these filled the F40 niche in the offering, in all 3 tone woods many different woods with both flat and arched back options in 'hog and maple.
It looks to me like the most extensive offering of F40 variants they ever listed at once.
F45ce was also present in '85 at least as Acornhouse can attest, and I think that lead to F47 coming back in early '90's, but when you look closely it looks like all those "F--CE" a/e cutaway guitars are based on the F40 "16 lower bout F body.
While the 47 specifically is absent from the '96 and 97 ctalogs, it was present on the 2001 list ,and was offered in Corona as well.
And New Hartford.
SO.....not to steal the thunder from our new members' find, but the 16" lower bout F40 is actually a Guild staple that they've revived in many forms over the years.
