Thomas Streetin registered his first mark on 15^th August 1794, as a plate-worker, going on to register other marks up to 1820.  He had been apprenticed to John Lambe, who was a prolific maker of sugar tongs.  The first of his marks was in a rectangular punch in 1794.  He then registered a circular or oval punch in 1798.  He appeared to have been registering circular and rectangular punches at the same time.
