Hi Tony,
After further examination of photographs, I believe that I have an answer for you.

This photo from #33 shows in the top right corner a second He 162 in the A Shed with ropes from a hoist attached to the engine nacelle.

This photo taken from the opposite direction shows two He 162s with Air Ministry numbers in front of a placard identifying BV 155 B and a distinctive wall pattern behind it.

This BV 155 B is elsewhere captioned as BV 155 V2 [the prototype of the B model]. Note the identical placard and distinctive wall pattern placing a BV 155 B with He 162s that went to England.
best regards,
Jim
