This is a nice, unique bicycle adjustable wrench, featuring the center slotted square nut adustable wrench area, for very small nuts or bolts, or perhaps some other special purpose. It is marked "WINN & TIMMINS". It measure 4" long overall, closed. A nice clean wrench with a few spots of minor pitting, and stamped with the intials A C on one side. Jaws work smoothly, no damage, little wear, or minor dings on the edges, clean, but darkened steel finish. A rare wrench because of the name on it!
