Sorry to be a pain but I just am not getting anywhere with the last four clues: I am grateful for all the help so far given by the way.
Many mouths nourished (6)
Equipment for miserly gamblers (4-6,6) (this is the number of letters given to me)
Many animals slaughtered (8)
Do you think that the answer to Unisex head preserver with a Welsh connection could be CARDIGAN? Not sure about this though.
Thanks to you all
