The Proctor was a military version of the pre-war Vega Gull. Some 250 Mk.I planes were used by the R.A.F. as communications aircraft. Mks.II and III were equipped as wireless-operator trainers as was the MK.IV which differed in having a larger cabin and longer fuselage. Complete wireless equipment was installed and the direction finding (D.F.) loop in the fairing above the cabin was used for flying on a radio beam. The Proctor IV was also used as a four-seat light communications machine.
