As always thank you Bob.
My only contribution is that the barrels do not appear to have received 3rd Compulsory Proof c. 1900, then again in 63'

Interesting that there is a 'LD' on the action flats. I do not know if Francotte sourced actions from Dumoulin Lambert

There is a crowned 'LD' on the action flats on another Francotte. Scroll down about 1/2 way

Is there a tiny MAGI on the right barrel by the rib, or is that part of MADE IN BELGIUM?
