The info from Browning says "finished by Lebeau-Courally," which seems an interesting way to put it.

I have a 16ga LC sidelock, and it's stunning.

Of course, the new LC sidelocks start at $40,000 or so, I think.

So, if the Browning is a real LC sidelock, it's a steal. The "finished by" makes me wonder if it's not made somewhere else, then sent to Belgium for finishing.
