Follow up: Cool Hand Tom's: Clarissa guitar acoustic, the back has a slight bowl effect.
That looks like my first guitar I bought in the early seventies. It was cheap, about 35 Euro's...
It had a classic headstock but mine was steel stringed.
Can't remember that the bridge was adjustable.
The bowl effect on the back was a bit SG styled.
I think it was a very fine beginners guitar, and it was just a bit smaller as regular sized ones.
I'd like to see some photo's of it.
I have a black & white one but that could be any guitar with a classic headstock.
