I just bought this Frank mossberg bicycle wrench , and it's in pretty good condition overall with little to no real wear on the jaws.
But the lower jaw is missing a lot of finish and the thumb wheel is worn smooth.
I can see how the finish would be corroded off the backside of the mobile jaw if laying on that side for a long time , but how do you wear the thumb wheel smooth without putting any wear on the jaws.
How could the mobile jaw finish and thumb wheel be worn this much without putting hardly any wear on the rest of the wrench ?
I am thinking the mobile jaw belongs to another wrench, but maybe there are circumstances that could lead to this kind of wear ?
