Good idea i will give this a try, like you say cant lose anything asking.
I sent pistonheads an email, but they couldn't give me the owners contact details, which i though might be the case so the helpful guy at pistonheads passed on my details to the owner instead.
Having looked closely at the pics on PH - I know where that is
+51° 41' 16.01", -4° 41' 59.56" - not sure if pasting this into google maps will bring it up - but its a property known as Waterwynch, between New Hedges and Tenby
