My frined dropped a rifle off with me the other day, fo rmy brother to drill and tap for scope mounts. It is a 20-inch barreled, 3/4 tube mag Model 336 CS in .35 Rem. I've never handled too many Marlin levers, other than the 1894 .44 Mag I had several years ago. It sure is a neat little rifle! Serial number is J15### Did they make many of these? I haven't seen too many .35s with the 3/4 tube magazine.
