Propeller identification help

[Tizzard]

20241028_191718.jpgI have the centre section of a 4 blade propeller which had at one time (long ago) been converted into a clock. The blade is stamped with the following and I wondered if anyone can point me in a direction regarding what it is from.

4 blades. Eight bolt mounting. stamped with 'LP 790 LH' over '80 RENAULT' over 'D2616' over 'P2520'. There are two approximately 21mm stamped boxes to the front which look like four boxes with 'A.I.D 151 in the bottom and something that I cannot read on the boxes above over 'BRI' I believe. Below these boxes is the Broad Arrow with an 'A' above.

Any ideas?

Thanks

Some photos would be very helpful, especially ones showing the stampings; also, showing what remains of the blades in order to determine whether this has a right or left hand thread.

Some images as requested. Thanks

Googling “LP790 propeller” turned up this result on another forum. (See photo posted separately).
For what it’s worth, I think the “LP” part refers to the Lang Propeller company of Weybridge, U.K.

Good evening, I have a propeller with exactly the same numbers stamped into it as the OP (see image) it also has some other numbers stamped into it, which I think are either G1280 (or G1260) N21 (again see images) it also has some AID marks.

From reading this post I believe the prop is either from a BE2c or DH6 as in the image above, I'm trying to find out more about it so that possibly I can work out what plane it may have been fitted to, I have tried searching for the G1280 (G1260) N21 but not found anything, I have also not found out much about Lang propellers, apart from them being bought out and becoming the Airscrew company.

In my research I have also discovered that many companies produced the BE2 series planes and the DH6 planes, such as Wolseley, Vickers, Bolton and Paul, and I'm guessing the engines came from a variety of sources, in the case of the prop I have Renault.
I have also done some research into the clock, which is a Smith 8 day floating balance movement, the dial is marked made in USA, so the clock seems to have been hobbled together with various parts and is about 60 years younger than the propeller.

Anyway if anyone has any other information, or places I can look for further information I'd be grateful.

Thanks.

WW1 British propeller manufacturing contracts were allocated in batches. G1280 is the batch number and N21 the number of the individual propeller within that batch.

Thank you, makes sense that they would have been marked for traceability.
