That drawing only shows the early type short blast tubes. The later ones were full-length and clamped to the gun at the rear.
Dives back into the mound-o-manuals...
The 5th image of the tubes shows the results of a resistance welding process as opposed to machine marks from rolling.Notice where the semi molten metal blasted past the plates edge.
Hope this is of help.
All the best
