I was in a General Aviation GB about 2 years ago here, and have built a few old type airliner kits recently. Right now I'm building a Turner Special in 1/32 scale for the Racer GB (Lindberg kit, liberal spares box, and plastic card) on now, but I would think it fits here.
Here are a few pictures of the airliners, and the engine/cowl and interior for the Turner Special, which is all that is done now.
