Per Tony Karsnia:
"The 68 Superior Pontiac Ambulance you see on eBay was bought new by Erie Mining along the North Shore of MN. There were two identical, a 67 that Jeff Damm has, and this 68 that has been owned since the early 90’s by a gent in Duluth. The mileage on this rig is correct at an original 9k. It was in service as a mine ambulance at LTV Mine in Hoyt Lakes, MN until 1991. The roof light is an aftermarket thing they put on, assumably when the beacon got lopped off on a garage door."
