Looks like the books were self-published?
(According to a Google search - Winterslow Pavey - in Books)
Maybe the family have some copies left?
"Winterslow, 1901 : 'taint like twer in Granfer's time." was written for the 1985 Wiltshire History Competition, and was a booklet of 4 leaves.
"People and families of Winterslow : [Kenneth John Pavey] remembering his childhood and schooldays during the war years, 1939-1945, when living at Timmens Mead, Middle Winterslow, near Salisbury, Wiltshire." was written for the same competition in 1989. 23 leaves.
Maybe a search for the said competition might prove fruitful?
