Note for all readers ...
When people quote values from the Charlton catalogue they are, as highlighted above, now two years out of date. Since then the actual market (or insurance) value may have risen or fallen - or simply remained static as suggested in the book for for this weight from 1993 to 2004! It is always wise, if using this type of info, to quote the Catalogue name and its date of publication.
