Jackson records Benjamin Tait's mark on a gravy spoon dated 1791. Usually his mark is recorded as having a serrated edge. Jackson does not show Benjamin Tait as listed as an apprentice, in the list of quarter brothers and journeymen or as a Freeman. He is however listed in the register of Dublin Goldsmiths, dated 1784, (spelt Taitt). This suggests he was working from at least 1784 and probably before. He is also listed as having had work assayed in 1787/88, but not in any prior or subsequent years. He is not listed under any of the other Irish towns and there is no other maker with the initials "BT" listed. The mark on the 1786 pair of tongs is certainly different to that on the other pairs. Was this an "unrecorded" mark?
