Al n- I believe that the MG Tickford frame will be too small (3 1/2 x 20). The Alvis is a full size convertible. Enfield Auto Restorations of Enfield CT 1 860 749-7917 or www.enfieldautorestoration.com restored a 1937 Alvis speed 25 a couple of years ago. They should be able to help you out with dimensions and picture of the window. I have a tool and die shop and have produced parts for my pre-war cars. If a window is not available, they would be no problem reproducing one if the dimensions and pictures are available. Once you have the dimensions check other british cars (jaguar drophead MK IV & V) sometimes they are interchangeable.

I have a 1938 MGTA TICKFORD rear window frame.Ifyou have a picture with dims.I could make one up for you. solid brass, chrome plated
