Hey Stefan thanks for posting. Have seen these images as well and wondered where in Italy this was taken. Also curious whether these are German or Italian bomb fins?
Just a side note. concerning the Photo's ..
Recognition is due to the Sikorski Institute and Museum - London.
I collect, therefore I am.
Nothing in science can explain how consciousness arose from matter.
Well after a little web searching these appear to be fins from RAF GP Mark IV bombs.
Would make for interesting cafe decor today. Quirky enough to attract the in-crowd!
