Yes, Browning has made the Superposed Lightning in Belgium.
A Browning over and under is worth about $1,000-1,500 on it own and the fact that it's a Belgium made Browing increases the price significanly. I would say somewhere in the range of $500 to $750 more. The belgium made Browning is the most collectible and popular.
