OK I figured out the problem. nothing is missing, there is a rear 'helical' which allows for adjustment of infinity focus. This was not tightened enough.

Now everything works, im not too woried about the aperture clicks, cause it is stiff enough without it.
Glass is really clean. What a nice looking lens now.

Wait, i just need to find the rubber grip now.. HONEY!! HAVE YOU SEEN A WIDE BLACK RUBBER BAND THINGY??...
