i have gotten a couple PM's about my open drums, so i thought i would post this for the historical curiosity. the two open rears, as you see are different. one is one piece, the other has the bolt on drums. sadly, they both have a rusted stuck bearing in the hub, so not usable unless one did the modern bearing conversion that has been brought up here in the past. the one piece drum measures in at .020.
looking at this stuff jogged my memory, and these came from an auction in western south dakota. the odd ball front drums with the big fin on them came from canada. any one seen these before?
