Those would be for the Model-A cars. The Model-T versions had part numbers (T-1387) on them, and were replaced by the A-17021 and B-17021 versions used through 1939, and then replaced with the 01A-17021 version. They did not have part numbers on them, which is why the measurement comes into play to ID them.
I've always measured overall length, because I assumed that was correct. Key word is "assume."Isn't the measurement typically taken from the jaw to the tip of the handle, not the overall length?





Thank you for posting these pics! I have one of these and have always thought someone wallowed it out to fit a big bolt or accidentally ruined it while wrenching. It looks like it just is really a poorly designed one and probably machined out of a smaller sized wrench to make it larger.
Indeed.There were multiple manufacturers making the pumps
But then, my daily commute, or @Snaparxon 's research drive, were far from the norm back then, more like two miles from the farm to churchI have read articles in those old trade journals and magazines, and from what I've gathered, up into the 1920s, automobile tires were notoriously unreliable. As in: repairs were necessary every 20 or 30 miles.




They are T-1917 band adjusting open-end wrenches that came in Model T owner tool kits.Thank you for posting these pics!

I have a few Ford marked tools but they're not too common. The Habitat store here seems to think they're worth a WHOLE LOT. I am going to work on a WWII Jeep toolkit at some point, and I've already got the air pump.
I'm sorry, but that is not correct. The square tang will not be found on the adjustable wrenches in correct owner tool kits for Ford N tractors produced from 1939 through 1954. If you look over at my avatar photo, you will see the owner's tool kit for my '52 Ford 8N tractor. Note the missing square tang on the adjustable auto wrench. There is no drain plug for the differential on these Ford tractors. It's a huge drain bolt that you often have to use a 24" pipe wrench to turn after they have not been opened for years.So anything missing that square tang (or the stub where it is), with a ford script, is pre-1926. Period, end of sentence, thank you.

The Jeep tire pump hose is quite long. Longer than one would expect for a vehicle with fairly small tires.
Hi, Jock. The Willys-Overland drawing for the first gen tire pump, A-6351 ('42, had a single folding bail foot), specified 24", but A-6899 ('43), and A-7511 ('44-45), the most common kind, as Don is showing above, specified 48". The specs, like most specs in the toolkit and accessories, were passed down from QMC (see pic), and then the Ordnance Dept (ORD) in turn, to Willys, and then Ford.The Jeep tire pump hose is quite long.
Willys and Ford supplied them at the factory. Willys suppliers were Arnold Haviland Co. (early), and later Fayette Mfg, and Walker Mfg. Walker the most common. They were made to government specs, and the suppliers were also supplying them to the QMC, and then the ORD, in turn, and QMC and ORD were most definitely using them for other purposes. Lots of Jeep guys are driving round with tire pumps that were originally in all kinds of applications, including cooking kits.The Ordnance Department supplied these pumps. Perhaps they standardized the hose length so they could be used on harder-to-reach applications,
I can't speak to everything larger than 1/2-ton off the top of my head, and I am about to head out to the flea market, but I am pretty sure the CCKW's had a DAPCO central compressor system built-in to the chassis serving air through a series of hoses to outlets....like dual wheels on larger trucks? The CCKW comes to mind.
The MWTCA.ORG is available on the Wayback machine, but the search doesn’t seem to work, like not finding Ford or Stanley in 2011. If you can remember more details, you can maybe meander your way there. The obvious place, Articles on Tools, does not have anything of Ford either.Way back in 09-10 I published my research on the MTFCA site on what constituted a Ford T tool kit
Wait,....what are we using for a reference saying that wrench is a Bonney? the "B" in a vertical oval? I know Bonney made wrenches for Fords and they made Z tools and they made CV wrenches that look like spark plug head bolt 5/8 X 15/16 wrenches like their 2525 with the Bonney Shield logo but.....Bonney among others probably continued to make aftermarket Ford tools even without a contract with Ford at that moment. It was a big market for decades.
Bonney made the nicest looking Ford tools by a margin. Not rapid-fire cheapo number driven production. Compare it to what Shelbylex posted. His is a true T wrench built for cheap, I have two myself.
Moore produced some rough looking **** shamelessly.
That script is later than T era and probably a later truck or tractor version. The head bolt size is the same as the T2335 but the spark plug size is smaller. Big spark plugs went out with the model A getting into production.
