that model looks perfect, but for a two torpedo sub that didn't work all that well... well I think it's very expensive, especially compared to the game's price!
But yeah that model looks perfect.. it's the later version though : the one used in the Sidney harbor attack.
The number of downloads of that minisub (12 for the version 1.3, 25 for the earlier 1.2 version) doesn't press me to perfect it any more than it already is, I have other things to finish in the Jyunsen B mod.
I'm currently playing around with video and sounds, I might just replace the intro video with the second one I posted yesterday, the fourth attack on a merchantman by I-10 during her 5th patrol.
