Roger Kessler passed away January 19, 2015. The site was taken down and then put back up for a short time and has since been taken down again. The article originally written By Phil Embury and posted by Roger on his website has been archived elsewhere on facebook including all the dates but without the photos Roger added. I have a copy of the article my self also. I also saved copies of his lantern photos before the site went down they were too good a reference source to let disappear.
