Earlier white anti-flash finish replaced in late 1967 by gray/green more suited to low level operations the aircraft now engaged in, though still with white underside with a high demarcation line. In an attempt to improve low level ride quality an experiment was carried out on a few aircraft, with the wingspan being reduced by the simple expedient of removing the outer section at the wing fold line. Although this mod created a slight change in trim it was deemed to be generally successful, and in time was extended to the rest of the fleet. A further mod was to attach launch rails for missiles to the truncated wingtips - these could accommodate either Red Top or Sidewinder missiles.
Built pretty much OOB from the Hasegawa kit with wingtips sawn off :-)
