Standard Tool Co. Slip Lock Speed Wrench
This is a nice old 12" adjustable speed wrench marked "STANDARD" on the slide. The marked is in a writen type script, so it is a bit hard to mark out, especially since it is a bit light, and some letter toward the end are only half stamped. This wrench is often call a Fitzall, the maker's trademark name for this style wrench, this is one of the first I've had without that Fitzall mark on it. This style wrench was patented in 1908. It is identical to the Standard Tool Co. specifacations. The spring loaded sliding jaw is in very good condition with good cross grooves for the lock to seat into. There is very little wear on this one, and I am sure you will be pleased with it's appearence. A hard to find antique wrench!
