I've got mine!
I finally called the importer/retailer I bought the Voyager from, and they'd received a bunch of little packages addressed to their customers along with the latest shipment from Moog. They hadn't gotten around to shipping them out to us yet, so I stopped by today, and picked mine up.
It's beautiful! Looking forward to seeing it on the Voyager!
So, if you haven't received your brass knob yet, it's probably still on its way!
