I would guess it would have had a valve UHF tuner originally ?
Yes. In its original form it was released as the VHF only TV125. The TV125U with (valved) UHF tuner didn't start appearing until the opening of BBC2 was approaching.
The difference in price was 8 guineas, the same as the difference in price between the TV125 and the TV125U. As the sets were still under guarantee it saved any arguments to retrofit the UHF for the price of the tuner alone.
Interestingly, though, the TV125 was only fitted with a shorting link on the plug and, presumably, your tuner is a later Bush one - because of the mechanical arrangements, including the push button unit, needed to fit the cabinet ...
