PRS-T3 Looking for white back cover

Hi everyone and happy to meet you !

I have an old sony PRS T3 ebook reader that still working like a charm, the only issue is the leather cover with back light incorporated that its starting to break.

Does anyone knows where can i get a new one?, better withou the front cover, only the back of the reader and without light... I know at the beggining at least in germany Sony sold the reader with and without cover, i guess the one witout front cover may had a back cover only...

Thanks in advance !
