What are these speakers worth 2nd hand?

[Mr Classic]

Been offered some speakers from a family friend and have been told to make an offer on them. Don't want to take the piss so I've looked online, seem to be going for £25 on eBay up to £40 on forums. Model is Tannoy Mercury S, picture below http://www.zenn.com.sg/Mercury-S.JPG

I think that you have answered your own question, If you can get them for £25 on ebay it has to be £25 or less.

Not much, these are not the Tannoys that their reputation was built on.
