Thank you for any help, have struggled with these.

[Mojo-Jo-Jo]

12a underrated

[writesbad]

12a underated

[boxtops]

There seems to be an error, underrated has 10 letters, perhaps the setter can't spell....

[Sam1960]

12a could be underrate if your e was wrong ?

[Anngel]

28/29 second word could be weight...but that makes your t wrong.

[TheWinner]

perhaps Bantam weight ???

[boxtops]

the first word could be weight too (avordupois being a weight system)

[boxtops]

^ I like bantam weight

[ladyalex]

28 &29 Market Weight

[TheWinner]

market weight is the correct answer, and well done ladyalex.

14a Recital?

[mallyh]

display?

[Sam1960]

14a display looks good
dis - reversal or absence of an action

[ladyalex]

routine ?
If every letter is wrong :-((

[JaneCarter]

Thank you Mark, did have a couple of answers wrong, now adjusted with your help!! 14a) turned out to be "dutiful". Crossword now finished.

[ladyalex]

Mark ?

14a is a very poor clue for 'dutiful' as it suggests that the answer is a noun rather than an adverb or adjective.
Happy to help all the same. :-))
