Hi
We have been given this propeller & would love to know more about it thanks.
Have supplied some photos so hopefully someone will know when & where it was built etc.
We would like to sell it so if anyone knows the current value that would be great.

It is roughly 8 feet long & does have some damage on the ends.
Thanks in advance for any help
Lil

Good Afternoon Lilly,

Your prop dates from circa 1912 to 1914 and was made by the British branch of the French Integrale Propeller Company for the French Maurice Farman aircraft. The stamp ADP indicates that it was intended for the British Royal Navy Air Service (It is an airworthiness stamp).

The data translates as:

MF Maurice Farman: the aircraft type.
IPC Integral Propeller Company.
RHT the prop was right-handed for use in a tractor configuration.
D2450 The diameter in mm.
P1750 The pitch in mm, the theoretical distance the prop would pull the aircraft through the air in one rotation.
HP80 The engine power.
Ren the manufacturer of the engine, Renault.
B23390 2 The serial number of the propeller.

With kind regards,

Bob Gardner

Lilly,

If you live in GB, polish the prop with bees-wax polish (bought in a tin from B & Q) which will enhance the appearance and protect the wood.

The insurance value of your prop is 2000.00 GBP which is what it would cost you to buy a replacement.

I'm delighted to be able to help you.

With kind regards,

Bob

Hi Bob
I will do as you say,I think I have some of that very polish in my cupboard as we do have some lovely wood furniture which I look after with beeswax.

Thanks for all your help on this. I am amazed how easy it is these days to get all this information so easily.

Do you know anything about old oars??111

Kind Regards Lilly

Hi Lilly,

Would you mind to post a pic of the opposite side of the hub (central part)?

Best regards,
Pierre-Michel

Hi Lilly,

Yes, it is exactly what I wanted to look at. Normally, the side with the "flared" central hole has to sit against the engine. So I think that this prop is a pusher misstamped RHT in place of RHP (with a P for pusher). It makes it more interesting!

Regards,
PM

Hi
in what way does it make it more interesting do you think?
I am enjoying finding out about the propeller as we knew nothing about it al all.

Regards
Lil

Hi,
All props which are not strictly standard ones are the most interesting: yours has perhaps a mismarking, which is not so strange (Bob had often said the workers who stamped the markings were illiterall...), but your new pics show that the way the laminations are glued is also appealing. Could you post:
- one pic of the whole prop on the same side of the flared central hole,
- and one pic of the side of the hub without marking (to look at the laminations and the way they are pilled up)?

Regards,
PM.
