I think I may have possibly solved part of the mystery surrounding Don's Stanley-BHM frankenstein driver.
I did some research to try to confirm my theory (see post #237) above.
As we all know, the first Phillips patents (2046837, followed quickly by an improvement, 2046840) were granted in 1936. Following suit, it makes perfect sense that the first Stanley catalog in which Phillips screwdrivers are introduced, as "new," was 1937. No mention of Phillips patent numbers or a license. The first Stanley catalog that cites the Phillips patent numbers and their license is 1940. The first BHM catalog that includes Phillips screwdrivers is 1940. No mention of Phillips patent numbers or a license.
All of that seems to jibe with my theory.
However, I am actually going to throw a 'shaggy dog barking up the wrong tree story' at you guys.
In every Stanley catalog I could find on IA/ITCL up through 1957, the part numbers for their Phillips screwdrivers are 25xx and 27xx and none of the shanks have that hex shoulder under the ferrule like Don's screwdriver, which has a different part number "H1823" and the name "CROSSPOINT". I could not find that screwdriver, by shape or by part number or name, in any Stanley catalog.
The 1940, 1953, and 1963 BHM catalogs on IA/ITCL all include Phillips screwdrivers, but none of the shanks have that hex shoulder under the ferrule.
Has anyone ever seen any vintage Phillips screwdriver without the Phillips patent numbers or at least a Phillips license number marking on the shank? All of mine - and that's dozens - either have the original patents (wartime tell!) or the occasional 1950 patent (2507231) that I couldn't read standing there at the flea market, and a license number.
Doesn't anyone else find it strange, then, that Don's screwdriver has neither marking?
The only cruciform bit screwdrivers I have without Phillips patent or license markings are Reed & Prince, which are Frearson, not Phillips. And guess what brand name they were apparently using? That's right... "CROSSPOINT"! We actually talked about it before on the Walden thread, starting here, in a bit of a fortunate mix-up that exposed the fact that Walden was selling "CROSSPOINT" cross-recess screwdrivers in the 1947 catalog, supplied by R&P.
I am thinking your shank might actually be a Frearson tip, not Phillips.
That would explain away the weirdness of BHM having to get shanks with Phillips tips from Stanley when they clearly had their own Phillips license, and might explain the part number that is not the part number Stanley used for their Phillips drivers.
It doesn't explain why BHM apparently had to get shanks with Frearson tips from Stanley, unless there was some kind of less advertised licensing scheme going on with Frearson, R&P, and Stanley (and perhaps others?) that we apparently don't know too much about.
The tip doesn't scream Frearson to me from here, though, so maybe the "CROSSPOINT" is just a coincidence in which case we'd be back to square one again.
I may be able to lessen your exasperation. I believe that your Crosspoint argument is likely correct. Both of my Stanley shanked Bridgeport screwdrivers have exactly the same markings.My head hurts. I can't find any use of 'Crosspoint' as a brand by anyone. Vintage technical literature abounds with this term as a synonym for 'cross-recess' or 'cruciform' without using the Phillips or Frearson name. The reference to "Crosspoint" in the 1947 Walden catalog, which is undoubtedly R&P (Frearson), and the "Crosspoint" marking on Don's co-branded Stanley/BHM screwdriver shank, might be vaguely technical/functional, not formal/proprietary, for the same reason. In which case, if it really is a Phillips design, not a Frearson, we're right back to why it doesn't bear the typical Phillips markings. Maybe it could be early, as I first speculated, in a pre-licensing juncture, before the whole licensing scheme was formalized. In either case, I am exasperated.


Even though the tips greatly resemble those of my #3 Phillips Stanley screwdrivers, I did a scientific test on a #3 Phillips screw. The screw didn’t fit the Stanley shanked Bridgeport drivers quite as well as the Phillips #3 Stanley screwdrivers.


The Black handle Stanley #3 only has the one early Patent number as opposed to the others that have the customary two patents on the shank.

It seems that Bridgeport did continue to buy shanks from others. When I checked my #2 drivers, one has the Bridgeport License no. 7 but the other has the Irwin License no. 2.





I’m a little sad about replacing my ORD engraved Bridgeport with a Stanley in my GMTK.
