I hope this may be of use to anyone who is sufficiently motivated or business minded;
The Cinema in the one-way system in Catford SE London has closed down. I enquired with the agency dealing with the site about whether the seats were still in situ, they said yes and were 'available'. That was until he found out that I only wanted ten, not 200. I don't know what the current status is regarding these seats, their design or condition etc, but I may be able to post the telephone number of the agency if someone out there feels they could do something with it.
