I am looking to resurrect a 1:50 scale Type IX U boat which I started 15 years back. Unfortunately the plan that I made the B & B model from is not that accurate. I am looking to bring this model (plug) to better accuracy before laying up. In particular I have seen at least 3 hull variants of this hull and am not happy which the correct one, if any of them. I am lookin to find accurate drawings of profiles and stern views of the hull.
