Archaeologia Cantiana, (out of print Volumes required)

I am trying to purchase three old volumes of Archaeologia Cantiana to complete the set held in the Archives of the Sandwich Town Council. The volumes required are LXVII 1953-4, Index 1952, and LXXVIII 1963. I have placed this query with a number of bookshops, to date without success and I wondered whether any members might possibly be able to assist? I would, of course, be prepared to pay the market price for any of the volumes. C.A. WANOSTROCT (Hon Curator, Sandwich Guildhall Museum).
