Yup, looks like a Montague. And the "Western Special" marking makes me think it was some sort of custom job. I'd think it would throw a 6wt line nicely, but if that seems to load too quickly, go with the 5wt SYLK. Also, are the ferrules pinned? If so, and you decide to replace them, you might consider replacing the pins as well (or have some rod restoration person do it for you).
