This mill rig came with my Jonsereds 111S and the owner did not know the brand...not do I. It looks like a Grandberg sorta, but it travels on 3, 22" rolls and the ends that holds the roll shafts and the vertical adjustment tubes are cast alum....very nicely made unit. I don't know diddly about CS mills.....anyone seen one like this before and know what brand it is???? Any other info would also be appreciated....THanks!
