Rossi model number 31 had a 4" barrel and was discontinued in 1985. Model 68 came with a 2 or a 3" barrel. There is no model 38 Rossi. Model 88 and 88/2 only came in stainless steel finish. They also had a 2 or 3" barrel. Rossi did make the "Rossi Double Action Revolver" which has no model number. It was 5 round in the 38 special caliber, came with 3 or 6" barrel, adjustable rear sight, fixed ramp style front sight, blued or nickel finish, wood or plastic grips, and was produced from 1965 to 1991. Since you are not able to find the model number, it is very likely this is the gun you have.
