I posted a Blog regarding an c1860 photograph I was attempting to date, based on the placement of a fallen bluestone and was rewarded with a contact; David Corio. It turned out he has several stereoviews of Stonehenge in his collection he was willing to share.

Included here, and linked to from numerous places are the scans he was so kind to send me along with the 3D Anaglyphs I made from them. (note: You need glasses with red filter over the left and cyan filter over the right eye to view an Anaglyph)
