When my previous computer crashed, I lost my book marks (yes, I know I should have had back up) One of the book marks was a site which had many pages. One was used 19th cent, used 1901-present, unused 19th century, unused 1901-present, among many others. The URL contained letters, not words. The letters I am almost sure contained "cmz".
All the stamp listings tied back to a current
ebay auction or BIN.
I realize this a long shot, but does this ring a bell with anyone?
Here's hoping.
