There are two different internal
arrangements in these valves, with vertical or horizontal structures.
The valve shown to the left has the vertical arrangement and is just
marked CV6, the valve on the right has the horizontal arrangement and is
marked VT232 and E1148 (this particular one is made by Hytron).
A slight variant in internal
structure can be seen in this Philco version, where the whole electrode
structure is positioned very high within the envelope.

There
are also different getter arrangements to be found. Here a mica shield
can be seen between the getter and the electrode assembly. |
 |
Shown
here is a cup-shaped getter, facing downwards, presumably aimed at
keeping the getter off the electrodes. |
 |
Another
getter variant, this time shaped like a tray. |
 |
Here
the internal structure can be seen - this example having a more traditional
wire getter carrier. |
