The 12th Stirling Air Engine rally will be held this year on March 25th at Kew Bridge Steam Museum. I attended last year's event and can report it was very popular, particularly the cafe.
There was a great selection of machines and engines and everyone was keen to tell you more about their creations. The Stirling Society awarded prizes for skill and innovation, last Year's Prize winners were Roy Darlington and Julian Wood shown below.
