Only reason I said mid 70's was that my Dad has been a life long fenwick man. Has all his rods he bought brand new (including an almost orange blank fenwick with metal ferrules). He can pretty much give timeframes on them all, and plan to show him the pics of butt. But I know that the 60's era had a different braid. But know it was around early/mid 70's they switched to that more brown/white braid on the handle. But definitely appears to be a pre late 70's model for sure. With that almost transluscent brown blank (as opposed to what Salmo said about the dark brown that they had before their buyout).

Looks like an awesome rod. I'd definitely keep it and fish it. I actually prefer to fish them instead of graphite for trout. I have an old Fenwick Grizzly blank that I built myself when I was around 12. Still has my old USA pflueger on it. Fishes great (but those were one piecers and you had to cut and put metal ferrules in). But still fishes good. If I were you, I'd buy a reel and take it trout fishing. Great rod, might as well use it. They are worth money. From what I've seen, and what you have with rod, it's well worth over $100. Not like having an Orvis Bamboo, but still a good find nonetheless.
