A 1980's ( 5 1/2 Inch X 3 1/2 Inch ) Black & White postcard sized Reproduction Photograph printed on unknown photographic paper with ' Short Gurnard Jupiter Eng N228 S10 ' written on the reverse in blue ink & showing the the Prototype Short Gurnard I ( serial no N228 ) Prototype Biplane Naval Fighter fitted with a Bristol Jupiter X engine which first flew in April / May 1929 ( Only one other Prototype aircraft was built the Short S.10 Gurnard II / N229 both of which where tested / evaluated by the RAF ) Thus we assume the original photo was taken in spring 1929. Photograph in good overall condition with just a couple of small light faint marks as one might expect. A First Class late 1920's British Military Photographic image with possible RAF Short Gurnard II Naval Biplane Fighter interest ? see scans.
