Research: Could these be Charles Dodgson Photos?

[David McGreevy]

I am researching these 2 photos, mounted back to back, from a British album dated 1858-1860.  They appear to show a boy's prep school with many students, a curious tree/metal sculpture or scientific apparatus, and a military bridge- building structure.

Both are arch-topped albumen prints, 196 x 146 mm.

The uniforms/ hats remind me of Dodgson's photos of the Twyford school, where Charles Dodgson's brother Edwin Heron Dodgson attended, and George William Kitchin (Xie's father) was headmaster....

Just delicious connections...

Of course, I'm 95% sure that this is just wishful thinking on my part, but would like some expert opinions or feedback.

Thanks so much, David
