Old Amfile (or other) cardboard 3x5 index card boxes

These 3x5 index card boxes usually have a mottled or marbelized black & white design on the exterior. They have a metal rod on the inside bottom, on which an adjustable metal plate rode to hold up agains the last card in the file. The inside width of these boxes is 5 1/4". Staples sells a newer version of these boxes by Globe-Weis, with plastic rods & plates, but the boxes are 5 1/8" wide on the inside. That 1/8" makes a big difference in getting the cards in and out of the boxes when full.
