I don’t recommend shipping any harp in its trunk. They are not adequate protection. The carton from Lyon & Healy has much more padding all around the harp and is infinitely safer. The bigger problem is local transfer people, so rather than have door-to-door pickup, you should drop it off at their main shipping office, and try to pick it up yourself. I don’t think one company will be better. Unless there are specialists in moving instruments or antiques, and you can find one, I wouldn’t do it.
