In response to an earlier post: My recollection is that there were not sufficient funds available for asbestos removal, so the rusted areas of jacket were patched with sheet metal and painted. The reference to "the steam chest on the fireman's side is split open and disgorging a menacing looking substance" in the first post probably refers to a split in the jacket over either the valve chest or cylinder, exposing asbestos insulation. I doubt that there is serious damage to the actual steam chest, but it's possible that the boiler is getting progressively worse with that asbestos still in place. It would be great to have it removed, and the jacket replaced in a way that the boiler surface can drain and breathe.
Here are some photos of #60 through the years:
