229 yes that was a typo
Actually PAC use various labelling schemes during different phases of construction
We have seen FC 10Xxxx used before on Block I is shown here from a few years ago
SP37 is serial production 37
FC10137
So FC10232 is going to be
SP32 or in the case of Block II 2P-32
So we can say that we have identified 32 x Block II units by Sep 2016 when this video was shot
