Mr. Caesar, while the pictures show us more detail, they don't tell us much more about the gun. You will still need to look at the proof marks to discover anything further.
What we can tell is that this is a side-plated boxlock with extensive but simple engraving. When new this gun would have appealed to those wanting the "look" of a high grade sidelock, but were lacking the entry fee.
The unfortunate gun seems to have been attacked by a hacksaw. In addition the front end of the trigger guard does not look to be fully screwed down, or is perhaps stripped. The "bronze" (paint? some sort of inlay?) work on the fore end is not original to the gun and has reacted with the barrel steel, causing an area of rust that is large enough to be of concern. Have the barrels checked very carefully before anyone shoots it. The original photo shows a poorly fitted butt pad. The gun has led a hard life in the hands of amateur gunsmiths.
It would be interesting to see what the proof marks have to say - any hope of getting some pics of them? While the gun has a decidedly Belgian look to it, the proof marks will tell its origin and should provide other useful info such as chamber length.
