This is a nice clean, adjustable wrench with the "K-9 M M MADE IN USA PAT'D NOV. 13 00 PAT'D MAR 11 02" marks on it. Although the Frank Mossberg Attleboro Mass. mark isn't on this one the K-9 brand, and the double M in diamonds, is The FRANK MOSSBERG CO. logo. This one is 9" long overall. There is a some minor wear on the jaws, but overall very good shape. The knurl and gear threads are all in good shape. Nice clean steel, not bent or damaged, no rust. This longer size is a bit more rare than the smaller bicycle wrenches Mossberg manufactured in the early 1900's!
