How to decode a 727 transmission?

[Geetex]

Count the sections with dots in them and that is number of months into 1961 the case was cast. Six sections with dots is June 1961. Ten sections is October 1961, etc. It is a 1962 model year transmission

Stumper, each dot represents a week in that month. With a perfect casting all of the sections with dots in them will have 4 dots, except one section will have between
1 - 4 dots. Using R/T Boy's example of June; 5 of the pie sections will have 4 dots and if the 6th section has 2 dots that will be the 2nd week of June 1961. Unfortunately, the castings aren't always perfect so sometimes a section of the pie that is supposed to have 4 dots in it will have less than that, so, assume that all of the sections have 4 dots except the last one in the series.
