Vintage…. Pure…. Aluminum…. Tube Cake Pan. Marked on the side “Pure Aluminum …Made in USA”. This vintage aluminum tube cake pan measures approximately 9 1/2″ top diameter x 2 3/4″ high (3 3/8″ high inside tube measurement). There are several scratches as well as some dinks in this pan; therefore, I have priced this item accordingly. In good, used condition.
