Fox *CVC* bocals are available in lengths 0 through 4, with #0 being the shortest length. Lengths #1, #2 and #3 are considered the "normal" lengths.
The standard plating is silver however nickel plating is also available at no extra charge. By special order only, gold plating can be requested at an additional charge.
*CVC* bocals are made with a nickel silver tube. They can also be made with brass tubes on special order.
