This folder was interesting, as it's a large set of drawings for different aspects of the bunkers in this battery, including separate drawings for the concrete reinforcement, electrical installations, water supply etc.
I didn't bother to copy all of it, as it's impossible to get good result with the combination of 75 year old faded drawings, strong downlight from the roof, large format drawings (up to 1,5/2 metres wide) and a compact digital camera with an amateur operator...
Anyway, it is what it is, and hopefully gives some value (those interested can always make the trip to Oslo to look at the material first hand, as with all other material I'm posting these days).
