I think it is worth mentioning, that Thompson rebuilt Thane of Fife as a pacific, class A2/2. Hornby did a model of this (R3831) in late BR livery. It showed up in Cat.66 (2020). This means that we have two quite different models of "Thane of Fife". There was another occasion when something like this happened. This was the availability of the LMS duchess class in streamlined and non-streamlined versions. This did not, of course, involve a rebuild of the loco.
