Go to the Marlin owner's forum and you can date the gun and find out a ton of information on the specific model. RC stands for regular Carbine. If it is pre-1955 it is not drilled and tapped. $1075 would be extremely high for my market (Atlanta) for a 336 in 30-30. I just traded for a pre-crossbolt safety 336 in 35 Rem from 1980 that was priced at $650 in excellent condition.
