Anybody seen one of these before?

Found this old Trackhoe on Craigslist, not to far from me. The owner says it still runs and digs. He says he thinks it is a Vermeer (due to it's color) but he doesn't know what model. It has a 2 cyl Wisconsin engine on it.

Does anybody have any idea what it might be?

Thanks,

Tim
