What is value of used marlin 336cs 1989?
The current value of these marlin rifles range from 275-350 dollars.
Your Marlin model 3082 was made in 1982 for Oklahoma Tire and Supply Co. (OTASCO) These versions used cheaper birch stocks, and are not valued any differently than a std. 336 Marlin, or a model 30 Marlin. They have no significant collector interest unless they are unfired, and then only minor value increases.
There is no accurate way to answer your question without knowing more about the specific gun. Most of the value will depend on the overall condition and exactly what model of firearm it is. There are also variances of value by region where the firearm is located. As a ballpark figure, a generic Marlin/Glenfield model 336 rifle in used good (80%+) condition should have a value of around $175-$250
