Guild F-50 or F-47

I'm wondering what the difference is between a Guild F-50 and an F-47?

The F-50 is sort of misnamed. It has a jumbo-shaped body. The F-47 has a grand auditorium shaped body. The F-47's shape is the same as the F-40, except it is extra deep (dreadnought depth) for more punch and loudness. The 47 comes in several models with different back and sides. The guys over at letstalkguild.com can provide more info.

I think there was a time where the F47 was in fact a mini-jumbo, although as of late it is the deep-body, Grand Auditorium size...
