if you don't mind me intervening … seems the wallpaper in question is a pic of "govăjdia blast furnace" … located in ghelari, romania (transylvania). while there are exact duplicates of sonny's wallpaper online … the version below (different lighting/camera-angle) is courtesy of wikipedia:
s'just different lighting/camera-angle … look at the iron-grate above the oven-shaft … etc. the other ones that are identical to sonny point to the same blast-oven. anyway … enjoy. nice touching bases with you, ussnorway and kemical … ¡arriba!
