Fallacy of equivocation, known in my day by the Latin 'aequivocatio'.

Then define 'meaning' as follows: grasp of the meaning of a sentence is
understanding of the conditions under which the sentence is true.

P2 then says that theory learnt in the same way, must be grasped as
having the same truth conditions. P3 says that the truth conditions
we understand a theory as having a different depending on its model.

There remains the possibility of equivocation between the sense of
'model' in P1, and the sense of 'model' (i.e. truth conditions) in P3.
