Tube chassis repair

["Earl W. Zwickey" <zwickey@arn.net>]

I would appreciate your suggestions on shops to use for repair of tube
type English formula car chassis.  As those of you familiar with these
are aware, nickel-bronze brazing is used, and I am interested in a shop
with a significant experience and expertise.  I am aware of shops such
as Prince in Illinois and Bahner in California, but am particularly
seeking first hand experience.

Thanks in advance,
Earl Zwickey
