In the case of the Z-19, I think the root cause is

4 mounting screws for the tube in the case had a support bracket.
This is the only mounting post that didn't shear from the rest of the
enclosure. The other 3 posts sheared off at their base to the
enclosure. Some superglue should be able to reattach the posts to the
enclosure so that the whole thing will be "like new". So this might
be something specific to this enclosure design.
I wouldn't use superglue. Try JB Weld, or some other 2 part epoxy, if
you can't find the JB Weld. I successfully repaired one of the mounting
posts for the power supply of an IBM PS/2 Model 80 using JB Weld.
However, I'm currently looking at a Tektronix 4115 that's in Illinois
and I'm in Utah. This is an item that would be "key" for my graphics
collection (and I've not seen one offered with any great frequency; a
local supplier has them but he charges $1200 minimum for these units
as costly replacements for mission critical systems). However, I'm
really leary of shipping it that far after my experience with the
Z-19.
Well, if the tube is only mounted on it's face then the mass of the tube
and gravity are creating a torque on the mounting posts. I have no idea
what a Textronix 4115 looks like, but could it be packed tube down?
That way the force due to gravity would be directly in line with the
mounts and wouldn't create a torque that would break them. Of course
all this is pointless if the packer can't pack worth beans. Even
further, if the box ended up being tall, it may get tipped over in
shipping therefore defeating the face down packing arrangement.
