The g2 has extended sides that are bent into a three sided open box.
Here the g2 shape is clearer.
The anode is the thin vertical strip on the right opposite the slot in g2. In operation g2 is normally connected to the cathode.

The thin glass tube envelope is 18 mm in diameter, and excluding the B7G base pins is 37 mm tall.
