I think to be clearer. I am really wanting to make a typeVIIC/41 . I have trawled the interweb and am becoming more and more disallusioned as I go on. I cant even find somewhere to buy another 1.72 kit. Nautilus models did a conversion, but it seems to be discontinued. I cant believe that with the amount of interest around about this subject, that some company wont bring out another model of this fine vessel.
