I am very interested in the Albion AM463, have been looking for an intact example for years and completely agree with you that it would be fantastic to show at airshows, even better if made serviceable and approved for use!
Ive was in the FBO business for over 35 years and museum work currently. I also work 15-20 airshows a year as a ground boss.
I would have killed to have had one for the RAF100 event we held at the museum. "The truck that won the battle of Britain" I always say!
Please tell me more about the project your working on.
