i also have few of these parts and can add:
-32133 misses the internal dome (i have an arrow without the rubber tip, you can see a dome (D12,8mm)
-32134 misses the cavity for said dome (the cavity has to be bigger to allow bouncing, the tip can be pressed)
-32080 has a hole through
-the common shaft has to end at the last hole (from tip to that last hole is different)
-"relaxed" still means trigger is unrotated
