This is a nice clean late 1800's patented saw set pliers marked "TRIUMPH" on the both handles undersides. Triumph was a Disston & Sons brand name or logo name. It has a patented split slide, the top part being controlled by the top handle, the lower be the lower handle. The amount of set is adjustable, as is the gauge guide, all the adjustments are in working order. This one measures 7" long. A very nicely designed, fairly rare model, by a quality tool maker!
