Gear Set
I found new but OLD stock cloyes double roller sprockets and chain for mine. I did wind up getting them as seperate pieces instead of as a set.
Judging by all the dust and package styling I'm guessing what I found is 40+ years old but brand new.
Someone here had a double roller set for a /6 in the classifieds. Actually had 2, as of a couple of days ago when I last looked he had 1 left
