The French usually specify diameter and pitch in centimetres. But,

A typical light aircraft prop is around 55-65" in diameter, with 40-60" pitch.

That would mean we should see one number in the region 140-165, and another in the region 100-150.


Based upon that, my best guess would be that the 695 is actually the radius (not diameter) in millimetres, the 200 probably signifies a 2-blade prop, and the 103 is proabably the pitch in centimetres.


So in inches, it's probably 54" x 40½", which would be about typical of the sort of prop fitted on something around C150 sized.


This is however educated guesswork having worked on quite a few French aeroplanes, and I don't actually know.
