Apology accepted, Robert, and I must try to improve what I am trying to say sometimes. It is often a challenge attempting to be informative and concise, or informative and so long winded, your reader either loses interest, or must combine reading one's post while eating dinner.
While I think of it as well, do you know if these reflectors came about solely within the realm of the evolution of the CMP, or was it already a preexisting feature on all, or some British military transport prior to the arrival of the CMP? If British use predated, maybe the answers for why they came into being hide in British military records somewhere.
