"I think the John Renbourn guitar is by Ralph Bown, not Bowen. They are top notch, I'd love one."

Correct on all counts, Eleanor. Clive Carroll plays one too. I am the proud owner of one as well.

I'm surprised nobody has mentioned Brook Guitars, a small company in Devon, UK. Superb instruments.

The TAMCO website lists many of the independent makers (not just UK).
