I don't know the owner, but Google
seems to know him - quick search for "amel 54 elyse" returned some posts on yahoo amel owners group from an owner (at least he was an owner in 2011) named Wolfgang Weber <webercardio@...>. Further searches for "Wolfgang Weber webercardio" returned proper email
address at <firstname.lastname@example.org>. You can try it, he either is an owner, or may know the owner. A bit more searching returns his city of Recklinghausen, using this as an additional info for search returns this:
Dres.Annette-Maria Feja und Wolfgang Weber
You can try reaching him by this number too
Don't know how actual this info is, but at least this is something. And by the way, marina people should have his contact details, can't understand why they don't call the guy...
