15 A.  Boer's mount led from Macedonia city (5)
   ?o??e
41 A.  Two characters from Skiathos mine part of boat (5)  s??g?
NB.  A lost letter has to be reinstated in some clues before solving. Also, two answers exceed their allotted space (letter count is entry length) and we have to find a way to accommodate them. I don't know if either of these clues is affected. Thanks for any help.
