Your Marlin Model 3079 was made for the Oklahoma Tire and Supply Company (OTASCO) in 1979. There should be a brass medallion in the stock representing the American Hunting Tradition with something that looks like a mountain man in the center. The serial number should have an "OB" prefix to the serial number.
These guns were made by Marlin using the Model 30 for OTASCO for several years. Marlin made two different models, the Model 30 and Model 60 for these commemorative rifles.
Value for these commemoratives will be about the same as any other Marlin Model 30 in similar condition and no more.
I hope this helps.
Due to the increasing cost of ammunition, there be no warning shot!
The growing federal deficit = generational slavery to the national debt.
