Raimey, I'd be very skeptical about V-C guns built in Belgium. If the gun only has the toplever markings, no Verney-Carron anywhere else, then it wouldn't be "their" wares. And V-C specializes in barrels. Has for quite some time. Produces them for other makers. Can't imagine why they'd go to Belgium for barrels. Maybe licensed their Helice system to someone in Belgium, or made actions for someone in Belgium.

Still a mystery as far as I'm concerned.
