This is a trumpet bell mandrel Ferree’s Tools #N91D. It is 24 inches (61 cm) long. It tapers from 1 inch (25.4 mm) to .480 inch (12.2 mm). It has a lot of surface rust and will need to be cleaned up, but otherwise it is in good functional condition.

The shipping calculator sometimes charges too much. If it is over by more than a few dollars, I will give you a refund for shipping. Also, if you purchase more than one item, I will send them together to save you money.
