Where does the " sp.107" designation come from ? It is outside the usual Hawker numbering system. Special projects ? Asking this, wondering about hypothetical Sp.106 or Sp.108...

Study Project.

They were things Ron Williams thought would make a good 'project after next.' He had been seconded into the Advanced Projects Group at Kingston, with other staff from the wider HSA, and thought the 'Hawker' team could try a bit harder, when he went back to work with them on the P.1154RN.

When the P.1127 and P.1154 were active, and later when the Kestrel became the P.1127(RAF), most of the team were busy with real planes, so there were fewer P. numbered projects for the 'next' aircraft, giving Ron his chance to push for longer-term projects. They ended around 1968 due to a design reorganisation. One of the last SP designs fed into the Hawk.
