It is like Christmas without the tree!! some of the other pics I have seen show what look to be new axle hub gaskets sitting in the corner. The manifests list extensive spares for all the machines.
The owner is trying to get a museum to take them, since these pics were taken the logos on the sides of two of the machines were cut out... I can not imagine anyone with a serious interest in the history of this expedition would ever do that, so they are probably hanging on the wall in some hipsters loft... or worse.
