Looks like satin nickel. IIRC, Taurus didn't make stainless steel guns in 89.
My 2 85 CHs are both stainless. Got one, new, in 95-96 for $234.
Got the other last year, used, with the early 85CH wood banana grips (was looking for just the grips, to put on mine) for $175.
Just checked the Mfg date on my used one with the banana grips. It was made in 93, which is right for an early 85CH in stainless.
