[GreenKeys] Paper (off topic)

[Chris Fandt]

Hi all,

I've got a pair of WU Desk Fax units which uses the same 
conductive-surface paper. Anybody know if the Teldeltos paper, or 
equivalent, is available anywhere in the Desk Fax form factor?

Have had those machines for 35-40 years. Now that I'm retired I want to 
add that restoration project to my huge heap of big and small projects 
I'd tucked away during my working career. Several websites have a good 
amount of history and info on them.

Thanks for any info on the paper!

Regards,  Chris F.
