This is an nice, clean, small size, early 7" linesman's splicing pliers with maker's mark on it that reads "S & H CO. U.S.A. MADE"  They are in good++ condition with a very tight hinge, no rust, no damage, little sign of wear on the crimp forms. This style has 6 seperate round shaped sizes for crimping or splicing applications on the one side. The larger of the round opening is .147" and the smaller .110" (measuring both with pliers in the fully closed and locked position).  There is a end clasp to keep the pliers closed, it works very well. I see very little wear, the serrations inside the two ovals look fine, no rust, nearly polished handles. A unusual style, antique linesman's tool in great condition!  We have not seen an example of this small size in the past 10+ years.  In really nice shape too!
