Gentlemen, I can't thank you enough for your quick responses and insightful information!

The find story goes, I was pulling up the sheeting in the attic above what used to be an outside porch. This little beauty was in a plastic sleeve tucked in between the rafters. Whoever put it there, had to have placed it and then sheeted over it.

I'm originally from the great state of Wyoming, but currently reside in Pennsylvania. I grew up elk, deer and antelope hunting out there and had yet bring my rifle back to PA. Now I have one that I can take out in the field!

I'm going to be taking it to a gunsmith recommended by a family friend soon and have him go over it to make sure it's in shooting condition. Whoever stashed it away greased the heck out of it so it should hopefully be in pretty good shape.

Thanks again for the info!!
