12 inch CRT monitor (Ashton Green BN8)

I am looking for a 12-13 inch CRT monitor it doesn't matter if its broken since I only need the outside shell,the insides I plan to give to a friend who will use them as spare part for their own projects.From the research I have done I have found that there are not that many 12 inch monitors so if you have a 14 inch CRT monitor I will happily take that off your hands aswell!
