One is 15cm high and the other 16cm's high (when closed).
Is this usual and if so why did HMV alter the dimensions I wonder ?

That seems odd. Both machines seem to have the same eschutcheon, neither motor board is flush - they are both the same - sunk down.

So from early 1949 the 102 case was based on the Columbia 9000. The main differences to the 102 were a deeper lid and flush motor board, so there was no need for a winding handle escutcheon. This information taken from the "His Masters' Gramophone" page 208.

When the metal motor board was discontinued, the new wooden version required a deeper case, due to the thickness of the wood, as opposed to the very thin metal version. So, over the production time of the 102, there were three different case sizes, the original for the metal motor board, then the slightly deeper one for the wooden board, and finally the one with the deeper lid and flush motor board.(the "E" and the "H"). I once attempted to replace the metal version with a wooden one, and found that sitting the wooden one on the metal side brackets brought the wooden board up flush with the sides of the case, and also raised the arm to the point where the lid would not close.
