I'm no longer sure--are they still 4-6-0's, or have they somehow mutated into something else completely by now? <:-/

I don't know about 1098, but the 1533 and 972, are both in line for restoration. Granted, it's time multiplied by money. The latter two are in possession of responsible organizations, so I don't fear for their well being. Other examples might have included the field of disassembled locos in the Pacific Northwest - I forget the owner's name. The road to Hell is paved with good intentions.
