07/31/2011. Remarks by Johan Visschedijk: "After the reinstatement of flying in Austria, Ing. Erwin Musger produced a development of his pre-WW II Mg 9 sailplane. Leopold Hager was responsible for the aerodynamic design of the new version which was designated Mg 19 Steinadler (Golden Eagle), and produced at the Josef Oberlerchner Holzindustrie (timber industry) at Spittal an der Drau, Carinthia, Austria.
Construction of the prototype began in June 1951 and Toni Kahlbacher and Alois Hasenknopf flew it for the first time on November 25, 1951, it was registered OE-0068 (c/n 01). Intended to serve as a high-performance sailplane as well as a trainer, it was like its predecessor fitted with a pronounced gull-wing and of wooden construction. Over 32 examples were built in four version, Mg 19, Mg 19a, Mg 19b and Mg 19c.
The pictured aircraft was registered in Austria as OE-0324, and its last operator was the Alpine-Sportflieger-Club at Leoben-Donawitz, Styria. After expiration of the CofA in May 1977, the aircraft was stored, however, in 1981 it was donated to the Vintage Glider Club of Great Britain, and transferred by road to the UK the following year.
It was restored to airworthiness by Eric Rolf at Moreton-in-Marsh, Gloucestershire, and wearing the British Gliding Association (BGA) registration BGA 2903, and the unique BGA identification trigraph ERZ, the aircraft was reflown by Tony Smallwood and Chris Wills at the Avon Soaring Centre (presently Bidford Gliding) at Bickmarsh, Worcestershire on June 5, 1983.
Since the photo above was taken, the aircraft has been painted and marked similar to its Austrian livery."
