I passed Ruislip LUL depot on a Central line train today 14/12/2015 and brand new Matisa tampers TMM775 and TMM776 were easily identifiable in the yard at the west end of the depot near the cranes area.
I also passed the depot on 8/12/2015 and one of them was in the yard visible and the other one was on lowloader in blue tarpaulin. I guess that was the reception date for LUL for these 2 machines.
Merry Christmas to all!!
