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,
