I too have a Holdsworth La Quelda fillet brazed that I only yesterday finally completed, or sort of completed (are any bikes complete? Don't eac h need a little tweeking? A part here or there?) and took out for a test ride. You can go to this site to look at it should you be interested. Thi s one has pretty much the orginal paint, some appropriate and inappropriate parts, and is curretnly set up as a fixed gear.

Thanks for the opportunity to show it off.

Cheers.
