Picked one up today in .375 Win and can't find much info on it. I know they were made in the 80's but I'm not sure what exactly the XTR means. From what I've gathered it was a sort of upgraded version of the standard model right? Better wood, finish, sights, etc? I'd also like to narrow the production year a little but when I typed the serial into the database on oldguns.net it told me it was made in 1894... So I'm guessing they use a different serial number range? Basically any info on this thing is appreciated. It is replacing a Marlin 1895M in .450 Marlin that was a pos. My new brush buster.
