I do too, but that begs the question of whether, =given= that the
instructor did this and the examiner allowed it, would the student be
legally able to fly a taildragger without a separate endorsement. I can
actually think of scenarios where this might occur, but it is not
necessary to do so in order that the question make sense.

As others have written, the student does need to go back, and have an
instructor that taught him in a tailwheel write an endorsement.

It also brings up another question. How would the student fly a nose
dragger, that he had never been signed off in? It is my understanding that
a student must be signed off in every different model of plane.
