Hey folks, I picked up this Marlin that has a really stiff action which I intend to do the full on cleaning and a new main spring for starters. I'm not previously familiar with this model and now that I've looked it over closely I still can't find a model number.
There is lettering on the top and left side of the barrel which show in the pictures. Only other markings are the word "safe" next to the safety. Of course I've pulled the steel from the stock to inspect for the hidden. So is it still hiding or does it simply not bear a model mark and ultimately... what is it?
Also what is "Smokeless Greased"?
Thanks.
