Identification help needed

[Chris jinks]

Hi recently got hold of a wooden propeller finally. I wondered if possible to help identify or recognise this propeller. its from a recent auction ,no markings on the hub.so I thought it was a copy or some kind of trophy win for the RAF,POSIBLY SPOR ,when i got home I removed the clock in the hope of fixing the clock ,what I found underneath the clock on face of the hub were markings, MALTA YARD, NO 116 ,D25?0 POSSIBLY A 5, 100HP MONO SOUPAPE.FOLLOWED BY P 26?0 POSSIBLY A 4. ,MADE OF MAHOGANY, length 256cm also has some art work which makes me wonder if some sort of trophy rather than a real propeller ,many thanks

I have been told its a really early propeller possibly for Sopwith aircraft ,even for a early naval aircraft'
Is it possible to find out with these markings. I have no means of identifying the markings many thanks
