I have located a 30" sheet metal slip roll in my general area. It's
about 2
hours away by car. It isn't new, looks to be solid old US. I have only
seen
one photo.

The seller states that there is no maker's name on it anywhere, nor any
nameplate data. Is there any way to infer the max thickness it can
handle?

He says there is surface rust on the rolls. I figure I can knock most
of it
off easily with a 3M pad and just use it. Does this make sense to you?

Thanks,

Can't help with the thickness but I currently have on loan an old 36" x
2" diameter roller slip roll, I would like to know its capacity. I got
it from my mate who had been storing it with a mate, the mate had it
outside and with no apparent protection. I put the rollers in my old 11"
x 40" lathe and ran a belt sander over them and they cleaned up a treat,
far better than the rusty things I got after storage outside. They did
the intended taper rolling job fine and I still have them taking up
space, must get them moved now the owner has more than ample indoor
storage for them.
