Article about: I went to a local Museum at Fort Perch Rock to have a look at the recovered parts of war time planes.. Just inside the Fort, was a big bomb (I love big Luftwaffe Bombs ) I'm researching what
It looks like an SC500PC . This was armour-piercing and used against shipping and fortifications . They were painted sky-blue overall ( of course, if the paint has been added post-war my theory goes out of the window ! ).
BTW, a very good reference to identifying German bombs can be found in 'The Blitz Then & Now : Volume 1' pp. 147 - 177 )
