10 years ago i bought, something so exclusive and so one of a kind, something so rare that it made so many private collectors and military museums salivating: brown leather flight jacket and pants of German ace pilot Walther Nowotny who was the most decorated pilot in the world. Nowotny was the first pilot to achieve 250 victories – 194 in 1943 alone, and on 19 October 1943 for propaganda reasons, he was ordered to cease operational flying. Reinstated to front-line service in September 1944, Nowotny tested and developed tactics for the Messerschmitt Me 262 jet fighter.
That piece among other items (SS, naval, infantry uniforms & headgear) was in private collection of US army intelligence colonel before he passed away about 20 years ago. Let me know if you're interested.
