Pistols are percussion and have Birmingham proofs. Both pistols function perfectly. The cocks hold on full cock and the folding triggers extend and close properly. The frames are silver color and are likely and amalgam of what used to be referred to as ""German silver"". The frames are very nicely engraved in floral motifs. The left side of the pistols are marked ""Bentley"" and the right side ""London"". The wooden grips are finely checkered. The backs of the grips have inlaid silver diamonds with no initial or crest. The case contains a bullet mold, and a very dainty screwdriver. Very beautifully made. Barrels measure 2.25"" and overall length 6.25"". Very good plus to fine condition overall. A very fine set of muff pistols.
