KG is going to be kicking himself all over the I.O.M. 
Oh dear!

Can I just say that, I have lived on the IoM for 23 years and I have never heard of Perwick Bay?!
I used to coach croquet at the golf club, maybe 300m away, but I have never been on the nearest road (Clifton Road) or walked along that piece of coast.
As a pennace, I will (on the next sunny day) take a trip down there, and try to capture a current view from the same viewpoint.
I'll also see what I can find at the library and museum.
P.S.
For the first 10 years, I lived in Ramsey, way up north!
