A rare pair of steel clamps for winding thread. Probably once fitted into a sewing box but have managed to stay together. c 1820-1830. French?
13 cm long with the screw in the position shown in the photo.
4cm at their widest.
In excellent condition- no damage and retaining a mirror finish. Some minor tarnish and the odd spot of rust-the photos make it look worse!
