Fantastic collection, but I too am surprised they were fired up after standing for all those years.all the oil in the “Mains” etc, would have been drained and dried.
So chances are, a complete new set of bearings, turned crank etc, will be needed.

Just think, a lifetime of collecting, and it goes in the blink of an eye.I bet the old chap would be turning in his grave had he seen what had happened to it all.
