There were a collection of instructions from LRH which were originally directed to the LRH Communicators on how to set up an LRH office. This is probably where the attitude towards the avoidance of things with a strong scent or perfume started. He had OT perceptions and was very sensitive to odors. There was also a period where he didn't want anything metal around, which again may have been due to some special perception or a temporary sensitivity that developed during an advanced phase of auditing or tech research. I have a vague recollection that this was fairly well known in the Scientology community and some people became more self conscious about metal hypersensitivity and perfume when they reached the OT Levels, having to take off their Clear Bracelets, etc. After the creation of the Commodore's Messenger Organization my impression was that the LRH Comms became kind of redundant and focused on cleaning, ongoing maintenance of the R Offices and refreshing his obligatory pack of Kool Menthols but the CMO did the heavy lifting of designing and constructing them. In either case, these kinds of instructions would have been circulating from the first moment someone anywhere set up an R Office and they were required in every org. I still need someone to explain to me how Kools don't stink, OT or not.
