There's a guy called Mr Lovett, 49 Feckenham Road, Headley Cross Redditch B97 5AS tel ???? 543796 who was recommended to me by a friend who had him make one for a pre-war Ariel he was restoring. He was very pleased. I have just received a 2 piece one from him for a rigid M20, 1939, and it's not bad. Bare steel, a few little things a perfectionist might spend a bit of time on (the crease where there's a flat section on the front left where the chain runs by, for example), but a good ridge where there should be, nicely done edges, a good fit where the two bits come together (not a hinge in this case) - and 75 quid excl post. This one wasn't for me, but I'd have been happy with it if it had been. Might be worth a phone call if a genuine bit doesn't come up Pato?
