Siddeley 200hp propellor hub

[RFC_Observer]

Just received a fantastic 2 bladed hub, the markings are as follows, if anyone can help;

'Siddeley 200hp'

and on the underneath of the hub;

'DRG AB 7031 (which matches up with either a DH4, DH9 or Bristol F2b)

D2750 P2530

The gun timing mark is still evident and there are bolts on one 'face' of the hub, along with the markings 'G660 N89' at the base of where each blade would start. Photos to come - if anyone has any further details as to who could have made it, when, and whether it's more likely to come off a DH4/DH9 etc, i'd be very grateful

Photographs of the markings - underneath 'Siddeley 200hp' it faintly says 'BHP'

Greetings,

AB7031 indicates an Air Board designed prop for the 200hp BHP SIddeley engine, later upgraded to 230hp and called the Siddeley Puma, both with RH rotation. It powered the DH4, DH9, Bristol F2A and F2B. It was the standard prop for these aircraft from November 1917 to July 1919.

G660 N89 is the batch number; number 89 in the batch of 100 called G660, which in turn suggests a contract date of early 1918.

I haven't identified any makers for this particular drawing number yet.

With kind regards,

Bob

Just seen your photos, which are excellent by the way. If only every one could send us photos like this.

Can you tell me what the small nos are above G660 in the four small squares? These are airworthiness stamps and the top line reads AID (for Aeronautical Inspection Dept) followed by a number such as 21, 385 or 21V, (altho' these examples are illustrative and not possibilities!)

A wooden ammo box? They were steel in my day and I have two in use as excellent tool boxes!

Hi Bob, many thanks - will do my best to ID the numbers above G660, but they're very hard to make out.

The box is a reproduction of a 1,000 round .303 box from the First World War, thought it would make a nice 'background' shot for the photos!

Unfortunately due to finances i've had to put this hub on eBay
