This is a nice clean, adjustable wrench with the "A-8 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 A-8 brand, and the double M in diamonds, is The FRANK MOSSBERG CO. logo. This one is 8" long overall. There is a few minor edge dings on the jaws, not bad. The moving jaw thumb screw/knurl is in great shape, works well. No rust, a faily smooth finish, some small dings noted on the handle, not bent or abused.  Has about 0-1.6" capacity between the jaws.  This is a sturdy wrench. This longer size is a bit more rare than the smaller bicycle wrenches Mossberg manufactured in the early 1900's!
