About as far off topic as I can get

I recently came across this listing on GB for a black powder 12 ga. double. https://www.gunbroker.com/item/876998876

 

The barrels are marked "fine laminated steel," meaning Damascus, and there is no manufacturer's name anywhere on the gun although there are some symbols that could indicate the gunmaker if one knew what he was looking for. What interested me is the proof marks which according to the NRA Museum website are British black powder proofs from the Leige, Belgium proof house. The foreign-origin proofs got me thinking.

 

I'm assuming that in the century between Waterloo and Ypres Anglo-Belgian trade relations were pretty good so I'm guessing that this gun was a low-end commercial gun built in Belgium and exported to the UK where it was sold in hardware stores and the like to those whose needs in a shotgun were of a more practical nature than a Westley Richards or the like would provide. Does anyone know if this is the case or if something else was going on?
