Another photo from Pintrest:

This photo shows a He 162 with an unpainted fuselage in the aircraft dump at München-Riem. (The row of trees are the same as in other pictures of the Riem dump). The streaking on the fuselage is identical to that on E3+52 which to my mind confirms Simon's statement that the crash occurred at Riem.
