The engine was a Crotch Island quarry engine (Crotch Island is off of Deer Isle, Maine), and ended up at as a display at a store along I-95/Route 1 in Freeport (where the Big Indian is now). Somehow our president at the time Joe R found out it was available, and so bought it as a display piece so that people would know that we were a railroad museum, around 1993.
Around 1998 or 99 we decided we didn't need it anymore, so we sold it to Beaver Brook in Mont Vernon, NH. I don't know where it is today.
