seeking uboat type VIIC and IXC plans - searching for copy of Fritz Kohl drawing

[scalemarine]

Hello all,

Does anyone out there have or know where a set of the engineering drawings by Fritz Kohl may be located. I would gladely purchase a set for type VII and IX, or good photo copies of these. It is my understanding that these are no longer produced? If These can not be found, Does anyone else produce these plansets? Steve Scalemarine@sbcglobal.net
