Actually, the maker's name wll be on the windows with a code number. It may to try one of the Companies that will make replacement windows from the old pattern, possibly cheaper
contact www.eeco-ltd.co.uk they can make you two new windows BUT they can only do this by copy and you have send off the windows,which means sealing up the openings for two weeks.i had three made and the only fault was they were slightly under-size (quarter of an inch in height) and i had to lift the catches to suit.they pick up and deliver.to measure for a price you need to measure the opening and not the window itself.
Miriad has all the plastic windows that are made by Polyplastics, l had three centre windows changed under warranty on my Ace Firestar, see posts on marks on front window previous posts.
