Thanks very much everyone.
Ever since I saw the pictures and 3-Views in Tony Butler's BSP, Fighters and Bombers 1935-1950 I've wanted to build a model of it. CMR certainly helped out on that score when they released the TF.1 kit, I bought three of them on the spot. One of the leftover kits will be made OOB, and one will be made into the RR Clyde powered version, they all had the same tail group.
This has just been the right time to build the first one. I followed this 3-View of it.
