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.
The P.111 was designed as the smallest air frame which could couple an engine (Rolls-Royce Nene), an ejection seat (Martin-Baker), and a delta wing. After a landing accident in which the retractable landing gear failed to extend, the P.111 was modified during its repairs to improve the flight characteristics, and was re-designated the P.111A. Four "petal" airbrakes were added to the fuselage to lower landing speeds and the undercarriage doors were changed to reduce the trim change. A long nose probe carrying a pitot head was added. The most immediately obvious change was the new bright yellow overall paint scheme, the P.111 having been unpainted or silver coloured. The P.111A soon gained the nickname of the "Yellow Peril"
