Length of RR Falcon

Hi, can anyone advise on the length of an RR Falcon 1, II or III – I need to know the length from the aft end of the accessories casing to the fwd end of the reduction gearbox flange (i.e. minus the prop shaft/boss).

Many thanks.

I’m comparing it to other contemporary engines for a book sidebar, and I have various figures for all (inches would be accurate enough), but not the length of the Falcon. Since the dimensions I have for the other engines do not include the boss/drive shaft, I need similar dimensions for the RR engine.

I’m not close to Old Warden but in the absence of a definitive answer I’ll consult the GA’s at the National Archives next time I’m up there.

Having re-read your post the overall dimension given above is not so useful; you could scale it with reasonable accuracy from the photograph on Wikipedia. How accurate do you need the answer?

Just out of interest, why do you need to know?

There is a Rolls-Royce Falcon III on display in the Suttleworth Collection; are you local?

Sixty-eight inches according to Wikipedia (not sure exactly what points this dimension is between):
