Need help identifying brake parts

[Firechickenzz]

Need assistance on Identifying what drum and hub I might be running.
36 Ford converted to hydraulic drums, I have no idea when. Drum and hub is 2 piece.

I also installed new longer wheel studs. Dorman 610-345.

Most likely is a "BRAKE DRUM - 40-48 PASS/MERC, 40-47 PICKUP. HUB MOUNTED BEHIND"

Looks like all cast iron, not a steel center like Ford. Maybe old aftermarket thing from Argentina
