Thats a nice piece, I'm always "eye'ing" things like this, soon as I saw it I knew I had seen one before on YT. In the area where it was listed was all farm land, all flat, sandy/loam no rocks, and an expansive area, the town of Colonie, NY was rumored to be or is the largest town by size, maybe some odd ball criteria or legitimately so, in the U.S.
The problem was people, most of it was densely developed, commercial business, too many darned subdivisions, now an international airport. There were some farmer hold outs for years and I still see vegetables planted, newly cleared areas not far from the airport, and 1 thats been there since day one, the soil alone is just incredible, you cross the river, steep hills, gravel, clay, good top soils, but rocky, shale outcrops, and all kinds of variations including clean gravel deposits with rich top soil overburden. They developed the easy terrain first, destroyed all the ag land, and now are pushing development in areas like where I live and the terrain is not friendly, no stopping this nonsense it seems.
Reason I mention, it this must have come out of one of the many barns that did survive, there was a large shaker colony/clan or compound/farm or what the heck you call it on the other side of the airport and the barns are something to appreciate. There are also some barns left scattered around, place where they recently built a post office was a farm house, barns and some fields, I'd have been happy to own that place, suburban farming, in that soil. Relative to speculation of where this one was found, had to be one of the above, given the history of that area. One farm sold out and moved over here, bottom land near a large creek, I used to do hay up on the opposite embankment, I think they're nuts trading off that good ground, must have been a fair amount to give that up, the rocks I have picked off that field behind them are huge and seemingly infinite.
It would be a "right" fit for your museum or anyones for that matter, hope he put it back inside somewhere.
