Fenwick Pattison

Picked this up today as it caught my eye, it cost next to nothing for a signed original 60's piece of art.
I've tried the internet an not having much luck. The signature looks like 'Pallison' but on the back someone has written 'Pattison" which I think will be the one.
It's almost 37 inches wide incl. frame, and almost 16.5 inches wide. It's growing on me...would just like to find something out about the artist. Can anyone help?

Some more photos of what's written on the back.

Some more info via an email I received from someone who knew him:

Fenwick was known by me slightly and was a former BBC employee. He lived in a rambling barn, just out of Coniston village, and seemed very determined to live there. He sold antiques and specialist small items as well as his paintings, which I would imagine were not the main part of his work.
