The photographs are of the Vincenti movement from a superb miniature longcase clock dating from around 1900-1910 as a guess. The case is very heavy solid rosewood inlaid with satinwood shell and vase motifs and stands at 28 inches tall. The movement, apart from being filthy and suffering slightly from heavy-handed screwdriver work, is in remarkably good order. However I have not worked on one of these before so does anyone have any tips to enable the cleaning and servicing to go smoothly please? Also does anyone know the significance of the "RC" logo in the second picture?
