Propellor markings and diary

[sitsinthestands]

I have a picture of a half-propellor that was retrieved by Sgt Pilot Linden Richardson probably from an aircraft that he himself crashed while stationed at Beverley Aerodrome in WW1. The marks on the propellor hub are: DP 7100 (last two digits could be 66 or 06 or 60), HP 110 Clerget, Sopwith. We have Linden's diary of the last four months of his life which records his training and crashes so understanding the markings would help us pin down which aircraft it came from and which incident. A barometer is now mounted into the hub of the propellor and the diary records its date of purchase from a shop in Hull.

I would have attached it here but it exceeds the size limit for pdf files.

The prop is probably from a Sopwith One-and-a-half-Strutter and is likely to be a design of the Lang Propeller Co. DP7100 is likely to be either DG 710C or LP 710C, where DG would be Drawing and LP would be Lang Propeller; the company used both descriptions.

Thanks for the info Bob. Looking at the picture again, I would say the marking must be LP710C which would make it a Lang Propellor.

Hi Bob

I noticed from the diary that Linden says he got a propellor from a Camel C12 which he managed to turn over on landing at Beverley. Is this likely to be the same one or might this be another?

Hello Bryn,

The Camel didn't use the Lang Prop, LP710C and it didn't use the 110hp Clerget, so it must be another aircraft.

With best wishes,
