Uh, ya... about that Disney casting...
There are a few groups on the web dedicated to this (awesome) sub, and several issues have been brought to light with the castings, not the least of which is terrible quality control and a huge deviation, mostly due to inferior casting techniques, from the master model (which is absolutely beautiful).
I wouldn't use that Disneystore version for any sort of reference, but it'd make a nice display on a TV or mantle.
The plans call for an upsweep. I'm not sure of the exact degree, as I don't have my .dwg files handy here at home, but it's definitely noticeable.
