G'day folks,
Since that lining is riveted, I'd think it unlikely that it would be just cork. More like a harder friction material, like the old riveted car brake shoe linings. Or cork facing, bonded to a harder backing.

There's a small pic of this lining on this archived website [unfortunately the detail page wasn't archived],

Cheers,
Gadge
