These old cast covers were used on some 0-290s and possibly 0-235s. They also fit 0-320s and 360s. After looking for years I recently bought a set from Mark Master in Southampton, Hampshire, UK. By the way -- he is a great guy and a fine craftsman. I am in the process of getting them ready to powder coat -- the idea is to have them look like the blue ones in the Leading Edge Exhaust ad but the blue part will be wrinkle black powder coat.
Have any of you had experience with these covers? I think they will be stiff and flat so probably will seal a little better than the stamped steel ones. But I'm wondering if all is OK when using them on an 0-320. I know they will fit but just looking to learn of any possible issue I haven't thought of. They are a little larger because the walls are 3/16 to 1/4 inch thick but looking at my cowling, that doesn't seem to be an issue. Please chime in if you have any experience with these kind of neat antiques.
