Looking for some "mundane" radio recordings

[leicanthrope]

Does anyone know where I can find some recordings of regular German wartime radio broadcasts? Music and the really historically important speeches are easy to come by, and I have already scrabbled together a respectable number of them. I'm looking for the more "mundane" stuff - commercials, news broadcasts, reminders to recycle your ersatz butter / axle grease and so on. Basically anything to make the iPod hidden in the radio shell sound more like an actual radio...

I'm unemployed at the moment, so y'all get double points for any suggestions for free resources!

Danke,
