Collector buying old cylinder phonograph records

PLEASE INCLUDE PHOTOS! Longtime phonograph collector is looking for old cylinder phonograph records like the ones pictured here. I pay very well for nice examples of any make -- Edison, Columbia, Oxford, Indestructible, Lambert, etc. As you can see in the pictures, there are many different types of cases. The cylinder records themselves come in several different colors – black, blue, brown, gray, green, pink, purple, light blue – and two diameter sizes, 2 inches and 5 inches. Most are 4 inches long, but a few are 6 inches long.
