If this is the same guy that's been in the clear Creek Canyon area forever (I remember seeing a poorly done replica in the mid 1970's), it is nothing more than a rubber-tired camper that this individual tried to fashion into a replica of Goose No. 2.
He used to drive it around Central City, Black Hawk and the Georgetown area. You would also see him camping along the banks of Clear Creek just off of Colo. 119 (Before gambling turned it into a major thoroughfare).
I at one time wondered what happened to it, (but not for very long) maybe the engine blew up or it was sold, or the guy just lost interest.
