Welcome to the forum. The knife was produced at the S&W plant in Houlton, ME as part of the American Series. It's a light, general duty knife with a 440 steel blade and a rubber handle called the Posi-Grip handle. That knife had two stock numbers, #6085 and #330400, but I have no idea why. They were designed by Robert Ferraro.

The knives from the 1980's are good quality, well made production products. Collector interest is minimal but I'm sure that means nothing to you since your knife is a family heirloom.
