I don't mean to hijack this thread, but Rusty's photo of the rusty hulks reminded me of some that I found in Michigan's Upper Peninsula on an anniversary trip with my wife a couple of years ago. These were found on an abandoned copper mine in the same area where the Greenfield Village's Mason was from. Although not Forneys, they still represent mining locomotives, including the blind flanges on the center wheels of the drivers of the 0-6-0 versions.

Anyone up for a restoration?
