A friend in North London is restoring a 1930 Talbot Darracq with a Cabriolet canvas hood.
He has all the frame and fixings etc, but the hood material while apparently intact has seen better days. The guess is that it might be usable as a pattern.
As the MX-5 O/C has a vast experience in finding the best results for hood repairs, I thought this forum might be an excellent start for a recommendation where he can find some expert advice and the correct waterproof hood material.
