Thought it might just be a faded black but after looking closer not so sure.

Looks to me as though 3/4 of it has been spray painted a matt finish silver. It is a single screw, wood handle so it's a 1981 or newer so to new to be that badly faded.
It looks to have been spray painted (badly) a silver color.
Two tone gray? I'll guess a Plainsman.

Faded black. No question.

Painted!
Look at the handles!
If it's not painted and it's naturally faded it's a nice score for the price.
Here's the ad if anyone's interested.

Painted silver. The paint looks to have burned off near the charcoal grate area and below.
