Once they are ready to deliver it all happens super fast. I doubt you will get anything by hassling them - either they simply don't know, or company policy is not to divulge shipping info. Believe me, i tried when we were waiting for the much delayed launch in this country. By the way, as you all know, our sigs were all rebuilt. My original sig had been sitting in storage in-country for at least a couple of MONTHS before the local launch, and no one knew anything, apparently!!!
Then, my new car took 20 odd days in construction, cause unknown, then it missed the boat with the rebuilt sigs, so the work around was to deliver me my original car at the launch. My rebuilt car was scheduled for delivery on the 29th December. Next thing i get a phone call on the 23rd December that the car is ready for delivery and would i like to pick it up on the 24th?!! Mad panic to arrange payment so i could pick up, since the car that had been delivered to me at the launch was on a loan basis. All just before Christmas.
Yes, the company bends over backwards with service, and the work around was pretty clever, but you are not going to get any info they don't want you to have.
IS Brown has been on the order list forever, certainly longer than i was, so a total of around 6 years at this time. I would be dismayed and astounded if he did not get the first or second D in this country!! Simon Hackett will be up there too i guess, but for different reasons.
Pity they don't tell you the ship, otherwise you could watch progress on
