Splines
I'm after the dimensions of the SBAC number one spline as fitted to the Gipsy major 10-2 crankshaft please. If anyone has got these I'd be most grateful. If people coud restrain themselves from saying Oh "XXXX" will have them without checking that would be great as I've already tried Shuttleworth, MOAF, Deltair, Fleet air arm museum, BBMF, and a few others
