Many thanks to you all for your replies, we have a couple to look at tomorrow - one near to Greens Norton ( village nr Towcester ) and the other a bit further out nr to Market Harborough. We have seen one at Pottersbury and are keeping that one in mind, we have tried several with no joy! Did not think it would be this hard in finding one! Will pos come back to you for the details of the one at Daventry, if no joy with these others. Thanks again and have a good christmas all of you.
Jonah.
