Excellent move, Mike!
The Aurora U-boat - especially after finished, with a decent paint job - is not a bad looking mold at all. Compared to the overall shape of the Nichimo 1/200 mold (which I assume is the more accurate of the two), the Aurora is substantially more gracile - that is, longer and/or thinner - however that just makes for a nicer looking model, especially compared to what Craig was able to get that Lindberg Gato/Balao o look like.
Speaking of which, Mike, if you can send me some more pics of Craig's fleet boat, I'll be happy to open a gallery entry for it, buddy!
Good plan, and keep us posted, Mike!
