Sorry, but I'm overseas, and I expect that sending the mics that far would likely cause internal damage to a degree as ribbon microphones, especially vintage ones where the ribbon will have hardened and become brittle are very fragile.
Good old-fashioned ribbon mics are rare nowadays, and have a very strong character which many good studios will crave if they are attempting to get a yester-year sound. The fact that they're B&O would generally mean they fetch even higher prices!
