From memory the Proctor was an evolutionary wartime variant of the Gull. Kingsford Smith flew a Gull somewhere. Also I think the Gull had a Gipsy 6 of 200 HP and the Proctor a Gipsy Queen of 210 HP.
I think it was Joe Palmer who took me for a ride in a Proctor when I was a kid. He also owned a Staggerwing Beech which I also had a ride in.
