Weird. Even now that you have shown me that auction I can't make it come up in a search! kodak 70mm kodak 2405 aerographic none of those terms produce this in the resulting list of items. No wonder I didn't know it was there. Stupid ebay. [On edit: oh it looks like it's because he won't ship it outside of Canada, so ebay doesn't bother showing it to me here in the US in searches, though of course with the actual auction number I can see it. ]
(That's 70mm double-perforated Double-X for those keeping score. The auction doesn't use the term Double X but you can read it on the label.)
