old Kohler Home Butter Maker churn, hand-crank paddle for glass jar

Antique hand-crank butter churn (no jar, just the metal lid with attached crank and paddle), marked The Home Butter Maker, Kohler - Chicago. It's 7 1/2" from the underside of the lid to the bottom of the 5 1/4" x 3 1/2" paddle blade, and the screw top lid measures 6 1/8" in diameter. This works fine, a little stiff, but no locking up or stuttering. There's light surface rust to the metal, it could use a good cleaning and oiling.
