I have shipped a couple of these over the years - I always had good luck
by removing the machine from it's pedestal entirely, and shipping them in
separate boxes. Also, fixing the locking bolt down on the typing unit
before shipping is critical.
Once the 33 is in it's 'tabletop' configuration, it's very easy to pack
it up nicely, and the pedestal, being just light-guage sheet metal, also
travels well, if you block it from being crushed.
In the case of the original post, however, all this depends on the
relative skill of the Seller - and often that is sadly lacking.
Cheers
