This is a vintage butter churn dasher, with wooden paddle on a steel rod. We think this is made to fit a Dazey butter churn, hand crank or electric.
The wood paddle measures 4 1/4" long and 4" in diameter. The dasher (rod and paddle) measures 11 1/2" long end to end. There's a little light rust to the rod, the wooden paddle is nice and tight.
