Needed: Pictures of Racks

[cavertevans]

I am working on a writing project about Racks and their use, and I am need of a few pictures. Would anyone be willing to send me pictures of:
1. A rack with spacers
2. Spacers with set screws in them to lock them in place
3. Long frame racks with more than 6 bars
4. Racks with square bars, or just a picture of a square bar

If you are willing to take pictures, I would love to hear from you at: cavertevans@gmail.com
Pictures will be credited in the final product, I just do not have any racks that have these features, so I can't take pictures myself! Thanks so much, in advance, for any and all help! And if you are interested in the project, I am happy to explain it to those who are interested.
