Wouldn't bother with the medical equipment ruse as a lot of it is shipped around. People take more care if they think the object they are handling is not particulalry common -- don't know why. I tend to handle strange things with more care myself so perhaps I am assuming everyone does the same -- I might be right, I hope so.Martin, your post was one of the best I've ever read on any subject on any saxophone forum ! Thank you.
If someone is sending a sax to me I always send them this link: http://www.cybersax.com/packsax.html
I sometimes wonder if writing "Please handle with care, medical equipment" would ensure more considerate handling. I mean, playing the sax can be very therapeutic, in a medical sense, for some people.
