That is a trigger based on the concave lower shaft, all trigger shaft constructions will have that. The only way to tell WHICH trigger it is would be by the sticker label that would have been at the very top of the stick before it was cut and or under that knob tape. M is the factory it was made, 75 flex, T is the shaft type (traditional shaft) and the E# is the player ID and V01 is for version 1.
I have seen some Triggers dressed as other sticks but it is more common for a Tacks stick to be manufactured with a low kick point, which would have an LK on it.
