Here you have my idea about the evolution of the KA tunics:
- M33 this looks like a standard WH M40 tunic with pleated breast pockets and outer pleated lower pockets.
- The M36 has dark green patches on the collar tabs, dark green shoulder boards, and pleated breast pockets with inside lower pockets. Usually with brass buttons.
- The M40 are identical to M36 except from the insignias that usually are with out dark green backing, and field grey shoulder boards. Usually with painted buttons.
- The M42 are without pleated breast pockets with tongue (little tip underneath the button) on the flaps, otherwise identical to the M40 model.
- The M43 are with out pleated breast pockets with straight flaps, and 6 buttons.
