I was wondering about that too, but he did say classic square bolt 30-30. Did Marlin ever make one of those?
Yes they did. Up until 1948 when the round bolt 336 replaced the 36. Still you can easily tell that's an 1894 he picked up in the video. The action isn't long enough to be a .30-30. At one point in the video, just as he's taking the 1894 off the rack, you can clearly see the pistol gripped 336 hanging on the bottom rung of the rack just below where he takes off the 1894.
