Yep, I have a stainless 3" Stratford too. Serial #7842XX. Slick, tiny, dependable and powerful little hide out gun. Mine rides in any J frame S&W holster.
My 1987 Gun Digest list the Bulldog as being available with a 2-1/2 or 3" barrel and both lengths in blue or stainless. No mention of a bobbed hammer.
