I personally would put less value on a Marlin built in the last few years before Remington, and the ones built by Remington just after the transition. This is from a using standpoint, not a collector standpoint, but I certainly wouldn't buy a Marlin as a collector in the first place.
If I was looking for another hunting gun from Marlin, I wouldn't hesitate to buy a later 2014 or 2015 model.
I could not agree more. The three Marlins I owned/purchased approximately 2004-2008 were all junk and none would feed correctly 100% of the time. I would buy a new model Remington without hesitation in today's world
