I have an LTS which is pretty much the same gun. The LTS was more limited in production numbers, 2700 made, but only chambered in 30-30. The Marauder was also chambered in 35 Remington and is the rarest of the Marauders. Depending on the market, which is obviously crazy at the moment, expect the rifle to fetch somewhere around $700. in 90% or better condition. My LTS shoots okay but it's not an accuracy king with groups at 1 1/2" at 100 yds. Most of my Marlins shoot much better.
FWIW, there are a lot of fake Marauders out there. The serial number should start with the letters W,Y, or Z. If not, it's a fake. Per yer serial number, the action was made in 1961, long before the Marauder came out.
