autogiro

A Cierva Autogiro was shipped over to Pitcairn in Philadelphia in Autumn 1928 www.flightglobal.com/pdfarchive/view/1929/1929%20-%200439... however this one wasn't registered until 1929 according to: www.caa.co.uk/application.aspx?catid=60&pagetype=65&a...

Pitcairn Aviation was located in Horsham Township, PA - about 15 miles north of center city Philadelphia. The Pitcairn facility later became Willow Grove NAS and later Willow Grove Joint Reserve Base. The installation closed in 2011 and is most of its land is in the process of being transferred to local authorities.

There may be some confusion about the identity of this autogyro. The famous 'Miss Champion' autogyro operated by the Champion Spark Plug Company was PCA-2 NC11609 c/n B-27. It was bought as a promotional machine in 1931 and '32, and was flown over 6,500 miles in the 1931 Ford National Reliability Air Tour. This machine was restored to flying condition in 1982 by Steve Pitcairn, Harold's son. In 2005, he donated it to the EAA AirVenture Museum, where many photos can be found online clearly showing the tail number as NC11609. The aircraft in the above photo was the PCA-2 owned by King Baird, which may be indeed be NC11608 c/n B-26, but the only other photo I could find of Baird's aircraft (damaged) does not clearly show the reg number, nor does the photo above. To further confuse things, the famous Golden Years database lists NC11608 c/n B-26 as Miss Champion, not NC11609 c/n B-27. Further info appreciated.
