The above are some very interesting and informative posts.
I have a Mansfield "Craftsman made" F335 acoustic guitar.
It is a dreadnought, and produces a very nice tone, albeit with some occasional string buzzing (may try to adjust this out by turning the nut at the top of the fret board. It is a very nice looking unit, in what I suppose is called natural colour on the top, with rosewood on the sides, and what I think is mahogany on the back. I have always been curious about the guitars origins, I know it was purchased in Canada around twenty years ago, but that's all.
