I have a Belgian Browning O/U over here I am trying to sell for a friend. It doesn't have much in the way of markings on it - other than the Browning name and that it was made at the FN factory. Fairly plain gun with a vent rib and shortened stock. With a serial number of #28154 and a non-selective trigger, I am thinking it a B27 - which is the improved version of the Liege. Anyone have more specific knowledge of the Browning Superposed's? Thanks. Roskoe.
