Sorry to bring up a old topic... But I just acquired a 2 pound 8 ounce Fulton boys axe head marked F8 on the opposite side in a group lot of other axes including a Plumb double (4), true temper 3 1/2 double, craftsman 3/2 (3 1/2) double, a Keen Kutter Connecticut single, two green Craftsman singles 3 1/2 and a Estwing boys axe w/ sheath for an absolute steal at a flee market style tag sale... The man said that nobody had even glanced at them in the two days they'd been there so far, so I got them for super cheap... It worked out to like a buck a piece! (The plumb is the only one on a handle, 28", well aside of the Estwing of course)
From what I can find in the little research I've done, is that Fulton was in fact made by Kelly, for, and to be sold at Sears under they're name. From the yesteryears tools site on the Kelly page it mentioned it near the bottom. Apparent they did this a lot for many stores (not just Kelly), they'd make unmarked tools and the buyers mark would be put on it opposed to the Kelly logo. Much like, for instance how a Marlin Model 60 is marked Glennfield model 60 for models to be sold in chain stores.
Here's a quote from that site-
"There is some conjecture that the FULTON brand name was used to honor Robert Fulton and his steam boat, a subject W. J. Kelly was quite interested in."
And from another site (can't remember where... I didn't save it)-
"A Single Bit Axe Head that is marked FULTON and F8 on the bottom in front of the eye, this was one of the markings used by the Kelly Axe & Tool Co."
I could be wrong, that's just what I found in my quick searches.. Honestly, I really don't care who made it, lol, it's a great little axe head that seems to be great quality. I'm eagerly looking to restore! Too bad someone hammered the hell out of the poll and it's a bit bent over... But nothing some filing won't fix.
