I would be fine with Komet, Penguin or Kormoran. I have a set of the Kormoran but it does not have the Bow/Stern view. It certainly is the simplest hull design. I have spent 8+ hours looking or either a 3d model or line drawings of any of these ships. Any help would be appreciated.
Morskie has plans for the Penguin and they're pretty good. You could also do the Atlantis with it. https://profilemorskie.com/144_PDF.htm Battlers has an Altmark kit, but may not be what you're looking for. https://battlersconnection.com/altmark/ Just some options for you.
there was a great Altmark at NATS this year. gorgeous boat. Call or email BC before you order though. I don't know how the fellas are doing right now, but they've been having a lot of life getting in the way in the past few years
I have uploaded this to the webarchive, plans for Penguin, Kormoran and Orion & Atlantis (=Ehrenfels Class Cargo Ship) in pre war configuration & plans for the Ehrenfels Class Cargo Ships sample: GA for MS Goldenfels (Atlantis) & MS Kandelfels
