Yes, three very different animals. I was on the search some time ago and had the same question, so I had a conversation with Hans about them. Hans told me due to the high number of daily questions he has not much time to chat about different models, so I allow myself to repost what he explained to me:
"
The '60s style F-30 body is more like a fingerstyle guitar with good definition and not a very deep voice. Really nice sounding in a 12-string. Not very aggressive. Bright and clear with not too much low end.
The '70s style F-30 body is more like a small jumbo; very well suited for fingerstyle but great for strumming. The deeper body gives it a nice 'low end' rumble, that some people like.
If you're a strummer, you should go for the '70s style but if you like intimate fingerstyle, the '60s style might be the better choice."
From my point of view I liked the look of the 60ties style much more.
Basically:
The 1968/1969
Hoboken is a physically lighter and smaller instrument. (similar to F30 body). 15 1/4" wide and 4 1/2" deep. 25 1/2" scale.
1970-1975 The
Westerly is a small jumbo built like a tank.
In 1976, the body size changed to 15 3/8" body width and 4 7/8" body depth.
Until the end of 1977 they didn't have any position markers on the fret board.

Are the f30’s from the 70’s small jumbo as well or just the f112 ?
