Todd, Mike, and Nick, THANKS!
Lew, I do not know. I have found pics of the early Brinly disks that look just like that. But, the Ohio Steel ones did too. To me, it looks heavier than the Ohio Steel ones. There are no tags on it. The front one is definitely a Brinly.
Randy, YES! That's what I want. Just can't find one. Maybe someday!!
