Thanks for all the help here. It would be difficult to find the reference in Brewers without help as the two relevant tables are well hidden.
Can anyone help me justify two answers -
5D Here you could crawl about 500m to finish (4) I can see how LIDO is defined by the first 4 words but can't see what's going on in the rest of the clue.
49A Huntsmen square behind doctor shunning plant fibres (7) JAEGERS but how is the answer obtained?
Thanks and good luck to all fellow solvers!
