Just a follow-up on the movie mentioned above: "The Last U-Boat"... Das Letzte U-Boot, Geheimmission Tokio.
Watched it tonight and it is... not bad and not good. No Hollywood effects

and very true to history.
A drama-documentary pretty well done. But you can live a perfectly happy life without ever seeing this one.
Model used in movie I'm not able to recognize. Possible a guppy - and possible a polish one?
Definitely a 1950's version, but I'm not familiar with these modern things...
If you, who reads this, wants the DVD, please PM me and I'll ship it to you.
But be aware that it's in german. With subtitles, yes, but these are for the english/american/japanese speech translated to german.
