Hi Jim,
the „WA“ on the burnt fuselage of the demolished He162 shown in the photo seems to be painted (over?) in another style than the letter/number on the opposite side of the black cross
In my point of view „WA+…“ was not part of a Stammkennzeichen for the He162 –but a temporary code of the Erprobungsstelle Rechlin (test center ) for planes during evaluation of the guns (WAffenerprobung).
So I have „WA+TA“ for Me262, WNr. 130 164 and „WA+02“ for Me262, WNr. 170 057.
Interestingly, Me262, „WA+TA“ later became „E3+32“ when equipped with BMW003 jet engines.
Maybe "WA+S_", (your assumption) could also be „WA+3_“ or „WA+5_“.
Oberpfaffenhofen fits as location, as the Erprobungsstelle was stationed there at war`s end and there is no problem with advanced types such as Me262 and Ar234 found destroyed there. Many Do335 in various states of completion were captured there.
As far as I know, no Do335 were captured at Neubiberg, but transfered later to this airfield.
