Found a few others on line all with gold clover on dolls head and same number on forend? See descriptions below
Made by R. Grove. The stocks, checkering patterns and engraving match exactly on each gun. There are no numbers on the guns themselves but the wood portion of the forends are stamped with the serial numbers 25302-2 and 25302-40. Each lockplate is engraved with pheasants on one side and ducks on the other. Various scroll engraving is also present on the lockplates, frame and triggerguard. Hammers are also engraved and click up nicely on both guns. Guns are opened by a top lever located between the hammers. Lock up on both guns is tight and positive. Birmingham proof marks are present on the barrels and on the water table. On one gun, the engraving is sharp but the coloration of the frame is gray. Edges and corners are sharp. The triggerguard has been reblued in the English style. The other gun has about 40% of the original color casehardening on the lockplates etc. The triggerguard on this gun also appears to have been reblued in the English style. One gun has barrels that are 28” long and have 12 gauge bores. Bores are excellent but with some very light roughness present. Bores are mostly bright and shiny. Externally, the barrels have nice high quality Damascus twist pattern present. The barrel is mounted with a large ivory bead front sight and small ivory bead mid-sight. The top rib of the barrels is engraved “R.GROVE LONDON FINE DAMASCUS.” Very fine scroll engraving surrounds the panel with the maker’s name. An gold shamrock is inlaid on each doll’s head extension. The barrels for the other gun are also 12 gauge but are 29 ¾” in length.
