note the full size fuselage roundel just behind the wing (no white outline), and the full size rudder stripes. Two bladed props on all 4 engines, the front cowling nose caps appear to be an elongated bowl shape, with 3 cooling holes, 1 below the propshaft and 2 above. I cannot see any sign of roundels below the wings. The colour appears to be overall PC10 or Nivo.
