Do you really have no old 12" monchrome portable TVs/monitors around? I
am sure you could find a CRT that would work.

I've got a number of CRTs here, white/green/amber, new/used, various sizes,
if the OP's serious, but I'm not sure how I'd safely ship one.

I'm
also toying with the idea of fitting an LCD into a VR201 cabinet
and although it wouldn't be authentic, it would sure make the system
more useable.
I am curious as to why an LCD in the VR201 cabinet is more useable than
the CRT. I can't see much difference in useability (but would much rather
have to repair a CRT_based monitor than an LCD-based one).

Wrap with 2 layers of large bubble size bubble wrap and then place in
a box and fill the voids with wadded up newspaper or peanuts.
This should be sufficient for any bare tube. For a tube inside an
enclosure, then you need to take a look at how the tube is mounted in
the enclosure. Some enclosures just have plastic mounting posts
holding the CRT in place. That's fine for the CRT sitting on a desk,
but not good when the whole thing is dropped 2 feet from the back of a
truck. In those cases, I suggest wadding packing inside the enclosure
to keep the CRT braced by more than just the mounting posts.

I'd add a layer on all 4 sides of polystyrene foam sheet (available
from your local big box DIY store as insulation).
Inexpensive and
something to add a little structure and to soften the bumps. Cut
it
with a serrated-blade bread knife.
