Rob Cunnigham brings word of an apparently unofficial patch from Ty-Ohni Lodge #95. I am tentatively assigning it a Z designation, but based on additional or conflicting information it could wind up as an YA or an A issue.
I have another odd item for you. Attached is a patch that was awarded to ceremonies team members in 2001. It was issued by the team adviser and as far as I can tell was not authorized by the LEC.
