For Argo44, The first line on the barrel lock says "CHOKE KL(E)D(O)I(T)O_" I can't read the last letter. The letters in parenthesis are possible alternatives to the preceding letter. The second line says "HEURTIER" which seems to be a French surname.
The triggers appeared to have been gold but much of it has worn off. The gun has a fair amount of normal wear. It appears to have been taken care of but has seen extensive field use.
I checked the link you posted. Not only is it like my gun, but based on the serial number, it is my gun. Pretty neat to see where it has been.
For the Rockdoc, The gun is light weight 6 lb. 1 oz. It is very nicely balanced and feels very natural when I bring it up to my shoulder. The barrels are 27 9/16 inches or 70 cm.
