No problem - if my spare ends up spare, you're welcome to it. If it ends up caver posted you might like to consider a miniscule donation to the NPC's Library Extension Fund in return for the help of whoever is kind enough to deliver for you. But if it gets posted via Royal Mail, just pay for that and we'll call it quits.
(Those who know me will tell you I tend not to look on such things as having monetary value; I just like to see items going to people who will appreciate them but might not be able to afford them otherwise.)
Anyway, sort it out between you fellas and I'll stand by for a PM from someone in due course.
