I'm from South Carolina and we surf fish for Channel Bass(AKA-red fish,spot tail bass, red drum, puppy drum and bull reds,etc.) I bought a couple of GK-60s in the late 70's to try. Not much to them. Inside is basically a copy of the penn number 9 but not quite as good.The only stainless is on the outside. Was ok but did not cast as well as the 9's. As with the 9, did best on 8 1/2 to 9 ft. rod and 3 oz or less. The penn squidder(finned spool) surfmaster and Newell's worked so much better with 10-12 ft. rods, twice the lead and in big surf (normal for oct.,nov.)
I still have one, and I have seen them on e-bay going for $15.-25. as well as some manuals. Mine has small head phillips screws on the side plates and a garcia style acorn nut on the handle, not the penn style nut with notches.
A search for garcia kingfisher + model # will turn up quite a bit including this site.
