This exhibit is a Type VT From Atlantic-Pacific Radio Supplies Co.

The anode is about half the normal size in this exhibit and so could be an experimental version.

Thanks to Joe Gruber for sending the images.

The balloon envelope is 44 mm in diameter and, excluding the UV base pins, is 104 mm tall.

Reference: Joe Gruber. Type VT was first introduced in 1919. See also 1919 adverts.
