This is a Marlin model 81 wearing a Sears & Roebuck brand name. Can't locate production dates for this model, but somewhere around 1940. I have an Over & Under "Ranger 103, 12 guage Shotgun. I haven't been able to find it in any of the books. I thought that Marlin made it but it wasn't listed as that either. Do you know anything about it? Bernie - The 103.13 is a Marlin 81. Made in the 1960's. It is a rifle, not a shotgun. It should be a good 'plinker' or small varmint gun, but has no significant value. Probably around $80-$100 in Very Good condition.
