I have the aforementioned Nav manual, once I have translated it from 1960's RAF into some sort of English I will try and give you an answer, could be some time! I can prob narrow it down to c or d, and most prob d although they appeared to be back plotted from destination, so that could be a spanner in the proverbial.
