Another addition: these are sample pages (posted by the seller on ebay) of a set of plans to build the Graf von Goetzen.
I know Pablo is tempted by the idea of building her, but it doesn't fit in with his plans/ideas at the moment, so perhaps the drawings could be used by anyone who feels inspired to (scratch)build the Graf von Goetzen?
and in case you did not know, the Graf von Goetzen was raised in 1924 by a British salvage team and brought back in service as MV Liemba in 1927. And she still is in service
