6/60-spline Beau bracket prop

Yes, correct, they did fit the bracket-type props on early Beaus. The same prop went on the Beaufort too, which had the same spline.
It wasn’t the same as the Spit prop though as it had to be a bit bigger to accommodate the larger No.6 prop shaft and the higher power. There wasn’t much in it though and it is hard to tell them apart unless they are side-by-side.
These bracket-type props were licence-built Hamiltons and were common on many 1930’s aircraft on both sides of the atlantic.
