N50 new owner help needed

I'm hoping someone might help with my mixer.

I'm going to pull it apart and service/paint thing to make it pretty for its place on the counter.  It's a n50, model 16472-m, which I believe they made from 1960s till the early 80s.

I oiled the 2 oil ports and ran it.  Seems a little noise in 2.  One is quiet.

It being older, it doesn't have latches to keep the bowel in place.  I tried a batch of cookie dough with the paddle.  When the dough came together, the paddle created a side to side movement which pops the bowel loose.  Is there anything that is suppose to be in the slides which takes up the play?  I see the clip is broken off which would keep the stud on the bowel in place.

I'm seeing the play between the pedestal stalk and the moveable bowel support.  

I think I'm going to find someone to paint the various pieces.  A bit concerned with keeping the abrasive from media blasting out of the all the inside parts.
