My faith in my fellow man is being restored. I sent a message to the seller of the Hermes on E-Bay with the typewriter packing recommendations I found online in the typosphere, and this was his reply :
I had it packed almost like you wanted it but after reading your request I opened it up again & redid it. Wadded newspaper all the way around it tight. Underneath & on top of the case is approx. 3" of dense foam. I know how postal carriers abuse packages. This one should be up to the test. Hope all ends well.
Have a NICE Christmas
