I have been thinking of getting rid of my Marlin 30AS in 30-30. It is in very good shape. The serial # is 13007502 which puts it being made in 1987. The barrel has the JM stamp. It has an Leupold VX-2 2x7 scope that is as old as I am. I sent it back to the factory to have it cleaned and serviced. Any recommendations on what is a fair selling point.
