Questions about delivery expectations from Ball Watch

I ordered a Roadmaster M Model A recently.

On Ball's site, it says I should expect a 6 month delivery.

I have also read about other customers' experiences, and how some deliveries have taken as long as 2 years.

For anyone who has ordered this particular model, is 6 months about right?

Also, as far as having it shipped to my house, are they requiring a signature. I am hoping so.
