Further to my post earlier today, attached are two examples of MkIX series calibration slips, one from 1944 and one from 1965. Only the ten degree stop corrections were given on the slip. The actual index error was a single figure printed on a ticket held in a transparent pocket on the front of the sextant’s case. Two observations can be made from the slips. By 1944, the UK had to be careful not to run out of essentials like paper and appear to have been using whatever was available, in this case a type of paper not much different from the toilet paper of the time. Also, as late as 1965, the RAF was still pushing the idea of an individual Navigator’s personal correction. How to find yours is also described by Dickey Richardson in the 1941 Edition of AP1234.
