propeller identification

[JohnR]

I have a 4 blade propeller hub marked Rolls Royce--G57n40---AD665MRH---
d3040p2980---275HP I am curious to find out what engine this is from and what plane it was on. I hope someone can help asap. Regards JohnR

Looks like it was designed for a Felixstowe Porte Baby airplane.

AD 655, 665, and 659 were all for that airplane, and the AD 659 model was also used on the Handley Page 0/400.
