Is it not possible that the man frames carrying the cylinders got moved around from loco to loco. I was thinking that a set of frames requiring extra attention during stripping for maintenance might 'miss' the slot for the loco from which they were removed and would end up on another Saint.
Larry,
I don’t think that would happen, as frames & rods would have to be kept together as a set, and were certainly stamped with the loco number. I’m aware of locos changing identity, but I think the frames
are the loco. Unlike wheels, boilers, brasses, etc, which were certainly interchangeable, and I’d guess interchanged, to minimise stock sitting around costing, not earning, money.
