Thanks to all that helped with information.

Based on the latest information from Axel E., he suggested Braeckers as being the possible maker;

Ets. Braeckers SA (=societe anonyme = plc), Rue du Crucifix 21 -39, Herstal. .... listed as "Fabricants des armes" = gunmaker.

I searched the internet and found this example. Although the pictures are not very clear, You can still make out the name "Braeckers" and "Herstal".

In addition, There is a monogram on the top of the rib that matches the monogram on my rifle.

Although the monogram is typically referenced as "EB", I think perhaps it might be the letters "BCC" which could stand for "Braeckers, Charles & Cie". (two opposing "C"'s with the letter "B" intertwined ? ? ? )

Also, there is a small distinct feature on the two actions that match on the guns. A small "raised" island that acts as a "stop" for the lever. I have not yet found this feature by any other maker.

As always, your comments are welcome.
