Hello .. odd request but having trouble getting rubber gasket for my windscreen to refit to Mark 5 Davrian (constructed 1970/71) . Windscreen seal should be should be 913442 for TR4/Spitfire MK1, 2 and 3 / GT6 / TR6 screen. The "chrome " strip I got was an identical T shape to my original but the rubber didn't seem to fit. The glass held up to the frame is not a good fit! Is there any way of identifying the glass as definitely Mk 1/2/3 spitfire? Image of etched glass info attached. Many thanks Neil
