Antique Brass & Oak Postal Scales

Set of Brass & Oak(?) postal scales. The weights are probably not original as they do not fit the holes very well but they are 1/2oz, 1oz, 2oz, 4oz. Scales are in good overall condition with some age related marks, though the brass needs a clean. It has "Made In England" & "Warranted Accurate" stamped on the side. Scales measure 8" by 4 1/2" and stand 3 1/4" tall (approx).
Any questions please ask.
