Here's one I've been scratching my head about:-
4 Down - "Town in Cornwall has different one 
in Staffs".  (6)  S-A-E-
    There is no town in Cornwall to fit, although
there is a village called Seaton (also a town in
Devon, of course), But, even so, it wouldn't fit.
Don't know anything about towns in 
Staffordshire, unless, maybe, the answer is 
based on "staffs", as in "supplies a workforce".
I hope that my "E" is correct, but even without
this, I cannot think what the answer is!
