Manufactured by Fabrique Nationale in Belgium for Browning's sale in the US. It is the basic Model 1910 with the 1971 changes (sometimes called the 10/71 or Model 1971). Most often referred to simply as the 'Browning .380 Pistol.' Not to be confused with the BDA-380 which was manufactured by Beretta and introduced in 1977. A few different finishes were offered, but a standard blue model in typical used condition will bring $300-$350. sales@countrygunsmith.net go to browning web site; go to services tab; you can look up seral number and age of piece.
