blu - you won't find such a thing, and are lucky to even find repops - didn't know anyone was doing the earlier ones - the ones from 50-something [3?] to 60-something are still available from stock, but I've heard they're also no longer being made
what I've seen regarding the Huck droms:
"these are getting very hard to find new, and used drums are usually worn oversized. The best advice is to not turn drums unless absolutely necessary. When our trucks were in everyday use, drums were almost never turned and rarely presented problems.
If grooves are cut into drums from over-worn riveted linings, new linings will eventually seat into the grooves. If the grooves are really deep, it is time to go hunting for new drums. One of my parts trucks had a drum split along a rivet groove. This is a good argument for installing bonded linings - no rivets to gouge drums."
you might search for some used and get lucky
