This exhibit is another VT from Atlantic-Pacific with an unusual bulb shape. Speculation suggests that this could have been made in Victoria BC as Moorhead visited several times.
The box for this exhibit. The size is about 50 mm square and 128 mm long.
Thanks to Joe Gruber for sending the images.
The wide glass tube envelope is 32 mm in diameter and, excluding the UV base pins, is 89 mm tall.
Reference: Joe Gruber. Type VT was first introduced in 1919.
