It's true that clean old collapsible Leitz lenses are rare as white 
elephants - but there's a way to CLA them.

I had found, for less than $50, a collapsible 50 summicron with scratched 
coating, some very light haze and dust inside and a corroded, very stiff 
focus ring. After a CLA at, the glass is now 
astonishingly clear and clean except 1 little dust spec inside (not in the 
centre, should not affect picture quality); and the focus ring is still 
slightly stiff, but is getting better and better with using. CLA incl. 
recoating and 2 shippings costed $300.

Seen this way, it's not impossible to have a clean collapsible 
summicron/summar/summitar for a reasonable price.
