Well, the last thing I would ever do is rub the DH mafia up the wrong way. Might come after me with a bit of balsa… :p
This list is not my own work – rather an amalgamation of others so I cannot take credit for it (or the spelling) – i’m just keeping the flame buring so to speak 🙂 But will correct it!!
It was not the norm for de Havilland to prefix part numbers with the letters DH. In the early years of Stag Lane design all drawings were numbered in a single numerical sequence. This covered types such as the DH 60 series, through to the Tiger Moth (DH 82) and Fox Moth (DH 83) etc. From memory, I think it was perhaps the Dragon (DH 84) which introduced a model designator in the drawing number but I would have to check if that is correct. Thus, the first element of the drawing (or part) number denoted the model, followed either by the drawing number or (for later types) a system designator and then a drawing number.
Thus, the configuration of de Havilland part numbers for the Chipmunk is C1-TP-313. This number denotes a Chipmunk part (C1) for the tailplane (TP). Other systems were denoted by letters such as CF (Controls, flap) and FS (fuselage, structure). Part numbers for the Dove and Devon start 104, the Heron 114, the Trident 121 etc. Strangely, de Havilland used to ‘pick and mix’ its parts and bits with Dove part numbers are still used on the Nimrod MRA4!
By the way, Whitley Project, the DH mafia gets terribly anal about the spelling of de Havilland – better not walk down any dark lanes for a week or two!
