All right, final update : they've reached destination.
Afore mentionned destination being the workshope of on of the most skilled restauration artists there is.
When I get them back (in a few weeks/months, I don't care for the delay, what must be done must be done with the most extreme care), obviously not by any transportation service, I will, indeed, as a thanks and an apology for the FUD, post pictures.
Thanks again to all of you
