Hi Keith,
Specialised Car Covers, West Yorkshire Tel: 01943 864646 made the cover for my Brooklands Ace.
Although they assured me they had a template for the Brooklands it didn't come out a perfect fit. In fairness, they offered to alter it if I sent it back with photos showing where it was tight/loose. But it does the job, so didn't bother in the end.
Quote "The Webflex-TLP cover is made from a special membrane that protects your car from rain, dirt and abrasion, as well as overnight dampness, due to special micropores that breathe, enabling water vapour to escape."
