The 6BZ6 is described as a semi remote cut off pentode (Variable μ) for use in television receivers within the IF strip. Thus it was designed to provide wideband amplification at 30 - 40 MHz.
Looking up into the envelope the inner grids can be seen. The third grid is more like a pair of beam confining plates, certainly not a wire grid.
The thin glass tube envelope is 18 mm in diameter, and excluding the B7G base pins is 47 mm tall.
References: Data-sheet. Type 6BZ6 was first introduced in 1955.
