The author included the Marlin 1895 in the list. But they should have listed it as Marlin 336 instead. The Marlin 1895, 444, .450M, and .308MX are just different caliber variations of the model 336. They're all the same rifle. They share the same receiver. The bigger bores have fatter barrels and fatter magazine tubes, and the loading gates and ejection ports are altered for each caliber. But those are the same types of variations used to offer any rifle in different calibers, including Winchester Model 70, Remington 700, FN Mauser, the AR-15.

It's interesting to note the Marlin has never had a break in production and is the only rifle in the list that is still being made.
