I wouldn't use modern braided lines with those guides.
I recommend copolymer, and the best I've tried is Seaguar Senshi
(though I really like Kamikaze lines from Australia)
(I can tell you to specifically avoid Berkley Fireline copolymer).
The nice thing about copolymer, it's soft and tough on the surface, and strong and hard beneath.

If you show the ferrules, we can probably narrow the date, and I'm guessing this rod is from the 60s, if not older.

Definitely late 60s

I wound 200 yds (!) of 10 lb P-Line fluoro on it and took it out today. I'll say that I can see why auto bails were invented for spin reels because this thing is quite the pain to use. The rod is a bit of a noodle, definitely not suited for setting the hook on multiple pound bass. Maybe better for finessing trout on 6-8 lb line. All that said I caught a couple of nice fish and enjoyed learning how spin fishing used to be.

Nice!
