well, if you can deal with a general catalog, you might try your library or a history type library...I only say this because I'm researching some cameras for a history exhibit now, and tried out the library where I work, and checked out a sears catalog today from 1897. There were bound volumes from the 80s back to previous decades as well, probably about a dozen in all.....
fwiw, I have a Montgomery Ward photo catalog from the 50s in my personal collection, and it's been a wealth of information when I needed it. The general Sears catalog isn't anywhere as detailed, for sure....
