Hi Dave and others,
This "Mercure" prop (modified Ratmanoff for me) is clearly from before WW1 and was modified also before WW1 : Mercure decals after 1917/1918 are different and during WW1 there was not civil use of propellers. As all military propellers have airworthy stamps, this one have to be made and modified before 1914.
In these early times, small propellers (from 4') were used. Look at this Chauvière price list published before 1914 : half the props are under 2,50 mètres (98") :
Regards,
PM
