Proctor constructors

for Proctor Mk 1,2,3 the parts are numbered KW for wing /centre section parts, KF for fuselage parts, KE for engine bay components, KC for control components etc.

Some were built from F Hills and Sons Ltd, Manchester and some from Percival Aircraft Ltd, Luton (especially the V’s). But don’t know the connection with the different prefixes (Ae, As, H, K).

Percival used a letter designator for each type,eg the Type D Gull, Type E Mew Gull, etc. These were further sub-divided to denote engine type etc and major new versions, so the Gull – which could have the Gipsy, Napier Javelin or Cirrus etc was the D.1, D.2,D.3 and so on.

When they got to “Z” they started over with Aa, Ab, Ac, etc. The post-war Proctors were the Types Ae and As. The pre-war Proctors were Type K (same as the Vega Gull) and I’m pretty certain that the “H” c/n signifies it was built by F. Hills & Sons in Manchester.

The post-war P. numbers were allocated retrospectively and never used by Percivals when the aircraft were in production. Edgar P used to get very hot under the collar over such things….Luckily on the few occasions that he rang me he was always very complementary about what I had written about his products!

One thing I forgot to ask him was what were the Types A, B and C … I have my suspicions but I’d love some concrete evidence rather than a ‘thin but robust’ theory!

Don’t know! But I do know that all Proctor V’s have Ae c/n’s if that is any help.
