McCauley Prop - C172

Looking at the TCDS and trying to figure out the difference between a DTM prop and a CTM prop in the model number. I know it’s unrelated to the seaplane prop. I figure climb or cruise? Just trying to buy a extra prop to get overhauled.

The letters designate specific design conditions. First link (61-00-01 Page 1) explains this and 2nd link (Page L-1) gives you a chart of the differences.
