Wow, that lens looks HORRIBLE! If it were me, I would have sent it back to them immediately - I am sure Mr. Christen would not consider that "normal" seeing those photos.
I agree with the others - send it back to AP - they will take care of it for you. You really need experts disassembling that type of lens. Position of the elements is hypercritical in reassembly, and almost impossible without the aid of an optical bench.
