Farmall Cub carburetor-need an ID

[flusher]

I picked up a 1948 Farmall Cub a few weeks ago. Needs a thorough tuneup.

I cracked open the carburetor this morning



and found this



I've never seen a one-piece annular float like this one. Naturally there's no ID on the carburetor and it's different from the 3/4-inch updraft IH and Zenith carbs that are shown in the Cub service manual. Looks like a previous owner found a 3/4 inch carb from some other brand/model tractor and made it work on the Cub.

Anyone know what carburetor I'm looking at here?

Thanks for any and all help.

Well, it looks like this carb on my 1948 Cub is some kind of Briggs and Stratton Flo-jet unit. The parts look identical to the ones from the Cub carb.
