I think that the "T" was just what came after the "S". And the Estes E motors are certainly the U-series motors (for "uber-D"). Then again, maybe not ...

A motor with the "T" is commonly referred to as the Mini motors

To add, as for "m" and mini, Centuri, too called theirs Mini-Motors, but used a capital M in the suffix of the motor designation versus a small m for MPC - eg, Centuri ¼A4-2M . Doug .

I'll bet that since 2 competitors were using the M Estes went with the T to be different All 3 companies came out with 13mm motors within a year but I think Estes was last

No, Centuri was definitely the last. Some time in 1973. I was doing my senior year in high school and was winding down my rocketry activities to a launch every few months. They were only on the market for a short while, and by the time I got to buy some more engines, they were off the market and they had switched to selling relabeled Estes mini motors. I managed to buy a bagful of mini-"B" motors in 1977 from a hobby store going out of business. Still have most of them.

I stand corrected on that - I do remember MPC showing off minijets at pittcon in 1971 and the following year Estes and Centuri having their minis advertised at pittcon '72 but maybe not in production yet
