17ac Mike herds eastern cattle from a long time ago.
Last one in, and I think it can only be one thing (def being the last 5 words); but I can’t fully parse it. The cattle bit is eluding me.
I agree with you about 3d. doesn't look right but may have missed something.
!7ac. There is a 2 letter ungulatel commonly used in scrabble. Put two of those in and you have an alternative spelling of the defined solution.
That parsing makes sense, tonipandy, but it would be another mistake. That spelling isn't in Chambers, and Google seems to think that it's a foreign word.
