Length and angle looks almost like the filler tube used on the early N series Ford tractors. I don't remember the bracket attached, though. The 6763 number is shown in the tractor parts book as oil filler tube part and both the A and B variant listed. No, I do not have any tractors at this time to verify. That N series engine was used in some light commercial vehicles, panel vans in the early 1940s. I wonder if it could be for that obscure application. And like Ross mentioned, these engines were used in many industrial applications. I once owned an N series industrial engine that had powered a generator.

6753 is the basic part number for an oil indicator boss gasket, road draft tube is basic part number 6758.
In the three parts catalogs I looked at (1948/56 Ford truck printed 1964, 1949/59 Ford car also printed 1964, 1953 Canadian Ford/Merc truck printed May 1953), the number is listed only as 0BA-6763

Bill's cited references, like mine, are for vehicles. I doubt that -a on your parts tag is a mirage. There has to be an industrial, marine, or some other goofball Ford reference that we don't have. Stu
Edit - thinking more on this, Ross speculated above that it could be for a military application that normal references might not cover. I've seen in my WW2 era wheel references that no military spec Dodge Power Wagon type wheels are listed. The same trucks were sold to civilians after the war, at which time the wheels got catalogued.
