This is the P221 Ai-Oh II that improves on the old system (P201 series).
Comparison with P201 Ai-Oh. The design is conservative P201 style.
New ratchet system is most improved point.
Old model needs two step operation. But one only operation for this model because of an automatic pull-up-down pawl.
The rubber band has two functions, one is a trigger spring and the other is a pawl spring.
10 rounds. Rubber bands are released by the ramp of a sharkfin-like releaser.
Made of MDF and unknown brown wood.
