Hi Marc,

To provide the correct answer I have e-mailed a wire manufacturer who manufactured that type of wiring when it was being made.

I will hopefully have an answer back in a day or two.

Marc,

I know it is called fabric-covered non-metallic sheathed cable, i.e., it is just an older style of NM cable, and *I think* the fabric *may have been* cotton fibers saturated in rubber *or something* ... but "I think", "may have been", and "or something" is not the answer I want to give, I want to give the specific answer.

The silver sort of looks like a metallic material. Interresting...

And feels kind of slick to the touch too.

I have sent another request for information to that company and to another company, either my first inquiry was lost or they have no idea who to forward my inquiry to.

Hi Marc,

I received this reply from Product Support at Southwire, the manufacturer's of RomexTM NM cable:

Some of it was paper and tar which looked like rubber. There may have been other versions as well.
Southwire

Not what I expected as I've seen the fabric-covered NM cables and worked with it, and, while I have see some which looked like that description, most looked more like fabric, more like cotton.

However, that is the answer I have received back.
