Friday at the 1500, I found a real nice 1990 year 1895SS 45/70. Great shape and is a real Marlin, not a Remilin. Even with JM marks, you need to be careful as some of the last jm's had some issues and I've been told that some of the first few remilins had JM marks. I think the only true way to tell is by the year made. Couple years before the split and you should be good to go. I'm very pleased with mine and paid less that most are asking now. Now to see how it shoots!!!!
I think you will love it! The first 45-70 I shot was a Marlin. That it what started my 45-70 quest. Let us know how it goes.
