WUB, sorry to say, no you didnt, cause the Meise wasnt even designed by Hans Jacobs in 1934, and appeared at the design competition in for what was to be Olympic sailplanes in Italy 1939.
There were well over 600 built during the war, and a few war built examples survive, there are no prewar Olympia Meise's left to my limited knowledge.
Sorry to spoil your claim....maybe you are getting confused with the Grunau Baby?
Like many others out there, Tiger Moth G-ACDC, but then she has been rebuilt several times in her long career, dont know if that counts!
