I disassembled this lens, because there was wobbling and sometimes autofucus moved little bit harder.
However... I was not able to assemble it back.
Before disassemble it was fully functional just mentioned autofocus thing.
Big parts are all there as you can see on pics.
But I can not guaeantee all small screews are there. 
Please contact me, if you would like to know more information or get more pictures.
