Marlin 336SC in 35 REM arent hard to find in my opinion. The conditions can range from poor to mint, and most of them are in the New England states.
Since I did a little looking, these guns are not easy to find since Marlin quit making them in 1963ish. My 1965 shooters bible does not list them. My 1961 shooters bible indicates the addition of a pistol grip cap. They were drilled and tapped as early as 1961.
I find your statement somewhat amusing especially about finding them (especially in .35 rem) in "mint" condition.
