Information received,
"Interesting photos. Immediate thoughts:
1. Certainly Rotol
2. Views are of rear of prop.
3. Metal alloy blades -almost certainly magnesium
4. In that case – possibilities include Spitfire II/Whitley/Halifax (not Stirling as this aircraft did not use Rotols) Miles Master
5. Given the location of the recovery, I would think it's a bomber prop ,therefore Whitley or Halifax (I noted possible remains of de-icing pipes, another indicator)
6. The blade chord measurement is in the right ball park but will not identify the blade drawing number and aircraft type. The full prop diameter is clearly not available.
7. If I were to be supplied with the distance between the hub centre-point and the top of the blade adapter nut (the castellated ring at the base of the blade) I may be able to provide a little more certainty as I have some spinner dimensions which would provide some guidance.
I hope the above helps the enquirer."
