Franck,
According to Llv34_doc over on LEMB, those two shots depict Me 262 A-2a W.Nr. 111 685 "9K+FH" of 1./KG(J) 51, found abandoned on the edge of the Hofoldinger forest, along the Munich-Salzburg highway. Here are two other pics of this same machine, published in Jet & Prop 10/4, provided by Neil on 10 July 2010 in his excellent as ever blog:
