This is a modular SLR camera bag system that I purchased sometime between 1986 and 1988. I never used it. I put it in a box with my camera equipment before I moved and completely forgot about it until now.
This was made in the U.S.A. at the peak of Tamrac quality. This system is very flexible. Carry as much or as little of it as you need. The bottom portions are interchangeable between the camera bag and the lens bags, which are also large enough to hold a Nikon F camera body or a flash. They can attach to the belt which is adjustable and very comfortable taking the weight off of your shoulders and back which also means you don't have a bag slowing you down. There are 2 separation pads for safely stacking lenses. There are D-rings for strap carry. There is a small zippered storage pouch inside the lid of the main bag. YKK zippers. It is clean and odor-free.
