It's an earlier one because the sleeve serves as the handle and envelopes the threaded jaw shank. On later models the sleeve was much shorter and lower part of the jaw shank served as the handle. No doubt the change had to do with production expense. Alloy Artifacts shows an example of this wrench, but no dating for it. It does show a 1921 ad having the later style. I ran into this distinction when researching a very early Harley Davidson adjustable. Because of this style, I'd date it 1910s or earlier. As to value, brand and condition is king. They generally don't sell for much because there's so many of them out there, and most of them have knurled jaw edges like this one because they were typically soft metal. The knurls definitely hurt it. BUT...most of what you see is the later style and not too many of these earlier ones. Plus, the tiny 4-inch size makes this somewhat of a novelty (most all the ones you see are 9"), and it does have a cool logo on it. I'd say value is probably between $8-$12. However, if this wrench could be associated as having coming from an old automobile, motorcycle or bicycle kit that was a collectible or highly respected brand name, it could raise the value, but that would take some research.
I like it! A nice find!
