Can anyone help provide the following information:
Diameter of front part of the engine cowling and number of gills/cowl flaps fitted on the above types.
The cowl flaps could number 14 but it's difficult to prove as most photographs of BOAC Scottish Airlines aircraft were taken at eye level.
The CAF's B-24A appears to have a different arrangement with the exhaust pipes projecting out near the top of the cowling.
