The DV-3 is a triode from De Forest that appeared in about 1925. It features a 3.0 Volt filament for use with dry cells. For dry cell use the filament must be a low consumption type, so not a bright emitter.
Thanks to Dan Absher for the picture and information.
The wide glass tube envelope is 32 mm in diameter, and excluding the UV base pins is  mm tall.
Reference: 1047. Type DV-3 was first introduced in 1925.
