If it hadn't said Blue Point, I would have guessed Stanley Hurwood.
Agreed, Beemer, as I alluded to here...
Probably by Bridgeport or Stanley, if I had to guess.
...but one feature of Stanley "Hurwood" drivers is the finned through-shank.
Here is one, at the bottom, same OAL as the Blue-Point I just found, and looking very similar, but not identical. The others are Bridgeport "Matchless," longer models, but looking more similar in the ferrule, and, no finned through-shank. (The older "Matchless" at the top does have a hex shaped through-shank, same purpose as the fins, as you know, to prevent the handle from turning off the shank.) I do have the same stubby size "Matchless" somewhere as the Blue-Point 153A and the Stanley "Hurwood", that I would've preferred for the comparison photo, but I can't find it at the moment. I suspect it's in my daughter's apartment. (The hazards of reaching for vintage tools as users.

)
Then again, the "Matchless" are square shanks.
So, perhaps they did source from Stanley, just not "Hurwood" or not including that feature.
