Check out Do-Its Do-It RSE-6-A Round Socket Eye Jig Mold although it mas a collar and barb, they are easily and temporarily blocked off with plumbers putty. Same with the Do-It WHJ-7-AR Walleye head.
Do-It SHWB-6-A Shad head and JMWB-7-A Minnow head are both designed for wire keepers but can be cast without the keeper and the little bit of lead down the hook is easily cleaned off.
