Older circle cutting machine

[sculpter]

I am trying to identify and find an older machine used to cut
large (12' - 36") circular holes in sheet metal. I have briefly seen one and
it uses two opposing cutting wheels to cut as the sheet is rotated. It
works something like a tube cutter. Any help in identifying one of these
would be appreciated.

Thanks Ken
