My last tenants have kindly cracked a panel on my internal doors and partition of my 1960s semi in the UK - alas the glass is "Spotlight" and is no longer made - I need a piece to fit a hole of 8.75 inches by 35.25 inches - does anyone know where I can get such a piece so I can repair the panel and then re-let my property? Any suggestions welcomed (apart from replace all the glass - ie 18 pieces all!)
