Thanks PBob!
Was a good place to start. But seems to turn out that the whole matter is,... let's say out of reach.
Some data can be found on different pages -mostly weapon price among lots of info-, and sometimes w/ total contradiction.
But also, not just the web: there are no books or essays handling this.
No (publicated) academic research. (Well the ReichArchive been bombed, so maybe it's a waste of time)
The only result is that I found a website that can show the exchange rates of about 40 or so countries.

(I've contacted my national military archive service, constitution -what ever-, asking whether there is some sort of financial report of the WWII era, but it's been said that they don't know about it. Lies or not, it proved to be unobtainable)
But Don can you please tell me something about prices set up in the game! Is it a good aproximation, or did you have some data on it?
Thanks
