This is a resin kit - If you have not worked with resin I suggest you research the different building techniques. The parts may require some sanding in order fit properly. You must use either two-part epoxy glue or cyano (superglue) adhesive. Both of these work well, so it is down to individual preference.
This is the third aircraft, designated 707A, WD280 was built for higher speed testing. Experience with the dorsal intake of the earlier 707 and 707B had shown that as speed increased, the cockpit induced turbulence which interrupted the intake airflow, so the intakes were moved to the wing roots. When the Vulcan appeared, it looked very much like an enlarged 707A. Later, this 707A was used to test the compound leading edge sweep subsequently used on all Vulcans. Although the first Vulcan prototype was already flying, a second 707A WZ736 was built to speed the development program, making its maiden fight on 20 February 1953.
