Hi CrustyRusty, Welcome to the Forum!
The Horrocks Ibbotson Ike Walton rods might be from the late 60s/early 70s. HI was purchased by Gladding in 1967 and became part of their US Fiberglass conglomerate. Your 8 foot rod has the more modern HI label. I have not seen a catalog listing for the Ike Walton rods, but hopefully a forum member has one.
Neither of your rods are marked with a suggested fly line, so the usual starting point for an 8 or 8'6" rod is a 7 weight line. Try a 6 weight and an 8 weight. The correct line is the one that is most comfortable for you to cast at your usual fishing distances.
Don't get hung up on what the rod is supposed to be, go with how it fishes.
Both rods have metal ferrules, which need to be kept clean. See this post showing how to clean them
