I just posted on the Lens part of the Forum to see if any of those lensheads had ideas about what Bausch and Lomb lens was used in W. S. Lively's 1909 camera, the largest camera at the time.

I have just learned about him - a prominent turn of the 20th century American photographer. In 1909 be built a camera to take 30 by 60 inch glass plate portraits. His 3 portraits were celebrated at the time. The camera was destroyed when his school of photography burned down in 1928.

The Eastman Museum has 2 of this ULF works and one of the negatives.

Check out the Youtube about a museum that has some of his works - and copies of the 3 ULF works
