Trent Haskins has created three blueprint files based on the Joans Supplement additional specifications. The design is done in original WC1 style with information taken from CGW and the Secret Missions. You can download a zipped pack of the three files in printable vector PDF format here.
I recreated these three blueprints of the Snakeir, Sivar and Star Post over the weekend when I caught a cold. It took about 2-3 hrs each with the exception of the Snakeir - probably closer to 4-5 hrs. I also fixed some errors in the original drawings as the fins on the Snakier were way off in the drawing, and some details were completely missing in other areas... Anyways, let me know what you all think... I know there are some other Blue prints out there that can be completed!
