Sometimes on schematic you'll see certain resistor being specifically drawn as a Carbon type rather than a metal type. I'm stripping an old project and found Carbon 1K resistors I'd fitted a few years ago but I can't remember why they were spec'd as CC types.
MrL's V CCS boards have Carbon resistors spec'd in certain places too.
Pourquoi?

Resistor composition?

How long is a piece of string? 
What are the two symbols then? Never heard of this before.

Grid stoppers should be carbon, or so I'm led to believe.

^ Yes non-inductive but ONLY if carbon composite, which do not have spiral track. Carbon film does same as metal film etc.
Oh right CC or MF, etc., I thought you meant there's different component symbols.
