Sir, – As a volunteer for Yorkshire Air Ambulance I have been given a set of Encyclopaedia Britannica, 1951 edition, to sell and raise money for the service. There are 31 books in the set and they are in immaculate condition.

This is obviously a series that would appeal to specialist collector or someone who likes a good set of books on their shelves. They can be delivered a reasonable distance in exchange for a contribution to YAA funds. Anyone interested please ring 01748-826022

John Ashton, Richmond.
