Type VII -- How much is it?

[themrwho]

Kinda crazy but I am curious about WW2 era estimated cost (adjusted for 2012 prices) of a Type VII submarine.

I did search a bit and checked the major sites I know of I found price for Gato class but nothing about U-boats. Since these subs are built by private contractors price should be published somewhere (similar to Gato class).

Possibly a German speaker can find this in 2 minutes but I already forgot whatever little Deutsch I learned in school, ironically except the first full sentence our cocky teacher thought us - ich sprache Deutsch

BTW I know 100 or so words from das boot speech mod but does not help with price hunt.

So if any book worms who happen to have this data
or
German speakers who might wanna lend a hand, please do so....

Thanks.
