Hi all, I am new to this site and have joined to get help from all you nice folks on a particular problem.
I have a second hand Four Seasons glass and alloy building and would like to know if there is anyone here who has rebuilt one of these.
it is the curved window type.
any offers of help will be appreciated and rewarded by credit on my website, chessspy.com.
thanks in advance.
