I own old Marlins with JM stamp up to new Marlins commonly called Remlins.
The JM's are coveted and will bring more money. Evidently when Remington first bought Marlin, the quality was poor. In my opinion, my "Remlin's" are as good as the JM 336's.

I don't mean to start a fight regarding the good/bad etc. it's just my opinion.

I prefer classic.
