PS: Look at the two pictures below. The one that shows 111728 before the 109 was dropped on top of it even shows the 728 painted onto the rear fuselage. Note the dark stripe in front of the vertical stabilizer that is also visible in the photo where the 109 is already sitting on top of the 262. They are one and the same aircraft and the W.Nr. is clearly 111728.
Cheers,
