Hi Jos,

Nice find. Thanks for sharing. If you have it in higher resolution can you then see if it is showing electrical heaters? :D

Hi, all

I don't want to start a new topic so i will ask my question here.

My question concerns the following.

I would like to know what amount of stahlbeton ( M³ ) , rundstahl ( kg ) and fromstahl ( kg ) was used to build a L487.

On a Danisch web site they only mentioned that this type of bunker consist of 2550M³ stahlbeton, I asume this number is correct?.

I hope that someone can help me with the information that i'm looking for.

Regards

Sander
