I am in West london (Harrow ish), so not a million miles away, I am happy to rescue these as they come about for anyone who can make use of them absolutly free as long as it doesnt end up costing me
and they are not sold on (which i am sure you would understand).
It seems to be the general opinion that these dont cost very much anyway, so it might be a matter of logistics (ie distance wise), Essex is a big place it just depends where you are.
If it doesnt prove practicle then I am sure I can find out a bit more perhaps even who supplies them, I will go in tommorow and see whats about and what I can find out.
If anyone else is interested then let me know here (keeping in mind my location and the fact that I dont actually have any right at this point) I will add an email address to my profile to make it easier.
Best regards
DP
