Steve, Those are, I believe, two different brake drums stuck together. Call the Rocky Mountain brake drum manufacturers, phone and information available in the Vintage Ford magazin advertisement. Also, maybe call Dave at Chaffins garage, he got me new linings when my brakes got hot and caught on fire.

Would anyone have an alternative idea on how to get break drums that will work with and original set of large drum Rocky Mountain Brakes?

Check with the current mfg. Get dimensions. I believe the drums are the same size, just not the preferred cast iron.
Buy a pair.

Hi Steve,
The RM drums are advertised as 11 3/4" and the one in your pic looks to be 12" ( the larger drum) I have no idea the width of the cast drums.
Have you giver any thought to having a metal fab shop roll a ring the correct width of 1/8" or 3/16" cold or hot rolled steel that can be heated to
fit over a RM drum so it shrinks to fit tight then welded & machined to the needed specs to match? At least you would not have to worry that it
was worn out?

Maybe the manufacturer’s name is spelled “Sunderland”. I still need one of these break drums to match the one pictured above.
