If you look at the Zirkus Rosarius Mossie, you'll see wheel hubs which were only in use on the early Mosquitos. I believe the exhaust stubs are similar to early daylight versions, as well. However, you'll notice T9+XB (?) has no propellors. If you look closely, you'll see the landing gear struts are just bits of metal to hold the aircraft up.

So, even if it is the aircraft which the Germans displayed, which I think is entirely possible, I doubt it was flown.
