This is a vintage glass Dazey #40 butter churn. It has cast iron gears with a wooden handle that turns the wooden paddles. It even has a fly trap! The glass is embossed with Dazey Churn, No 40, Patented Feb 14 22, Dazey Churn & Mfg Co., St Louis Mo, Made in U.S.A. The churn stands close to 14" overall, with the handle at its highest. The square bottom of the jar measures 5.5" x 5.5" and the sides expand to 6." x 6.". The opening has a 5" diameter. The churn is in good working order and the jar is in nice condition. The lid and gears have a nice patina. This would look great in your home or add it to someone's collection!
