Full set of encyclopedias (Old Coulsdon CR5)

Bought on a whim in a charity shop many years ago! Full set of 23 volumes plus index. Hardbacks, about A4 size. 1973 edition so information not exactly up to date. Looks great though. I am having a clear out so don't mind what anyone wants to use them for - decoration, an alternative to the internet, chop them up for an art project, whatever. They are really heavy (almost 2kg each!) so please only ask for them if you can pick them up with a car. Thanks.
