Plastics: Pre-War Seeburg Symphonola

I am looking for a sheet or partial sheet of plastic know as CAB Cellulose Acetate Butyrate AKA by the trademark name UVEX. I have not been able to this it on-line. Long ago some of the panels on the machine were replaced with UVEX now I need about 3 sq feet of red. The machine I have looks like the one in this YouTube video https://www.youtube.com/watch?v=hBwx6Ku-QLY The owner mentions he also used UVEX. Does anyone know where I can find this. Also, if you have a similar late 1930's 1940 machine I would like a picture of the interior and exterior of the back door with a shot of the, hinges. I have the upper back panel but not the lower door. Any help would be appreciated.
