Hi pegleg
A further clue to question 12, start with 4 letter word for a sailor, then reverse a 3 letter word meaning a large amount of cash which will give you the name of a bird which is said to be a thief.
Question 47, a4 letter word for a county + a 4 letter word for players. The whole 8 letters gives synonym for the last word in the question.
Question 49, a 4 letter word for fine linen + a three letter word meaning cut followed by a 2 letter word for the Queen. The whole answer is a machine.
Hope this helps.
