The main plate bears the serial number as published, and the train bridge bears the number 122071. I have chosen the former, as it is more likely that the bridge was swapped out as the whole main plate, although this also happens. This is seen in both the other watches. In all three cases, the numbers are a couple thousand away from each other.
Here are the other two, one that is certainly a Hudson Maxim, and the other a re-dialed HM, IMO.
It is noticeable that the sub second dial on the left is larger than the Hudson Maxim on the right, but only by 1 mm in diameter. I'll be restoring the HM next.
What do you folks think regarding the re-dialing? The HM dial is in poor cosmetic condition, tarnished and also rubbed smooth, possibly by some attempts to clean it.
