Propellor clock

[Sindabele]

I have a clock made out of a propellor. Can anyone please help me identify the propellor. On the top and bottom are the following numbers and letters:

DRG LP710C R.H.

D2740 P2360

100HP MONOSOUPAPE

AVRO

C1536 N15

Also on the back is the number 15. On the front are two small squares and 1 small arrows pointing towards the centre.

With thanks for any help.

It's stamped for an AVRO. It was built by Lang Propeller and used on the AVRO 504C, but that same design is listed for a DH5, Sopwith Pup, or a J&K.
