Lee, that's an interesting point about the filter being used since the 50s.....and (for better or worse) opens up a number of possibilities to where the basic air cleaner body came from. It would be GREAT to identify the actual host used by DeTomaso since adding snorkels would not be a big deal.
Two identifying features come to mind. First is the Goose unit's OD, which from Steve's link below, must be about 19". This seems to be 1 - 2" larger than a lot of normal Ford air cleaners, at least from the late 60s.

Second feature is the protruding inner 'ring' or 'bead' stamped into the air cleaner cover, maybe 6 or 7" in diameter. I don't see this type of ring when Googling Ford air cleaner images. All covers have stamped features of some kind but as far as I've seen, nothing to match what's on a stock Goose. My search has been FAR from exhaustive, but I would think at least 1 image would have popped up by now that showed a similar stiffening ring/bead.
So maybe we are dealing with an unconventional unit? (e.g., Ford marine or military part, (if such things exist?). Leftover bits from some 50s Lincoln? 1961 school busses? Econoline Milk Trucks? ….. I've always assumed it's a Ford part, designed to work with Autolite carbs...but trying to think out of the box at this point
