LesserSon, thank you for this information! I have several of these and, like you, have always wondered who made themI’ve speculated about these tiny beehive drivers, which usually have no markings.
This morning, one turned up marked Mayhew.
.So, do you think Mayhew made these for Disston, Disston made them for Mayhew, or a third party made them for both?
I have no idea. The "Monarch" name seems to be pretty well attached to Disston saw sets and to Mayhew screwdrivers. Monarch was attached to Mayhew screwdrivers as early as 1892. Your screwdriver seems to look a bit more like a Mayhew than a Disston.So, do you think Mayhew made these for Disston, Disston made them for Mayhew, or a third party made them for both?


There's still a lot of open debate about the "W.F." marking on vintage Federal screwdrivers.i assume the wf stands for war finish.
thank you ! good info..!There's still a lot of open debate about the "W.F." marking on vintage Federal screwdrivers.
For many years the wartime collecting community speculated it might stand for "WAR FINISH". Until I found one with the "W.F." marking and an Ordnance Dept stock number. Since then, more of those have showed up. Typically, "WAR FINISH" was a marking mfgr's used on tools sold to civilians on the commercial market during WWII, to show that it was inferior to finishes they would use if not restricted. Making a "W.F." marking with a Govt customer marking counterintuitive.
A smaller contingent speculated Wright Field, which also seems unlikely. That was a designation otherwise confined to Plomb and it was their convention, not assigned to them by the USAAF.
Inconclusive.

Argh, I was only looking at the 512 on the image he postedYou are right, RTM!
So then 666512 cannot be the correct patent.
The bottom line is a patent date, not number: “PAT OCT 15 12”

Same, because the marking in between "PAT." and "512" is not that great, or I may have gotten lazy, because I DO see the "1" in the "15" now upon closer inspection. So I literally went to DATAMP and found the patent ending in "512."I was only looking at the 512 on the image he posted

BLO over shellac? Did that dry OK? Or was the BLO just the lube for polishing? Looks good, mostly curious.
Looks like mine, very pointy. But all mine are labeled.







Coolest thing I've seen in a while on GJ! A close quarter offset screwdriver - that turns! I have a similarly odd ratchet. There has to be a set of beveled gears in there to transfer the power of the shaft to the blade. That thing is awesome.Anyone seen one like this before?
I added the longest MAC screwdriver to the collection yesterday. Now it feels like I'm working on a set! It's fun to try to spot the MAC handles mixed in with all the cheap copies.
I also picked up a big old DASCO stubby and found it in their 1926 catalog, listed as a machinist's screwdriver.

Based on that photo, someone has replaced the handle on this one, which probably explains the extra holes in the ferrule. I wonder if it was the same person who reground the tip. It's Here's another photo, along with a bent-blade Phillips I found and an odd Perfect Handle tool. I wondered if it'd been forged out of a screwdriver, but I kind of doubt it. It's a sturdy little dagger that's shaped a lot like an oyster knife.

It likely started out like this prewar Irwin with the hex by the handle. I picked up this one lately.




. Anyone know what this would be used for?
Well, it is on the list, a quick flip thru catalogs didn’t show it, but someone found it.I just can't seem to find any info on this screwdriver yankee no. 13 I see no. 12 and 11 I think but not a single no. 13 in my searches
