These 4 images show a parts movement with mismatched numbers. The barrel bridge contains the engraving for Fred McIntyre and is therefore the authentic part. The possibilities when looking at the back side of the barrel bridge and the top plate are that the pillar plate matches the barrel bridge, or that all three are different. The serial number is 146223
It is difficult, but not impossible to imagine that sometime in the history of this watch the train bridge was damaged badly enough to require replacement. In any case it has been replaced. The balance cock is yet another number and the balance still different, so the watch has been made up from parts.
