Is there something I'm missing ? Are 'cleaning marks' in the coating or
the glass ? If in the coating, would it be feasible to send it to Mr.. Van
Stelten and have it recoated ? Economically realistic ?

Jo & Tom -
In modern lenses, most cleaning marks are in the coating of the front
element, particularily on the early 50/2 Summicrons.
Jon Van Stelten does an excellent job of removing the old coating,
polishing and applying the newest flouride coating to the front surface
for about $100. Over half of the old Summicrons that I have seen
have some degree of cleaning marks on them but it doesnt always hurt
the performance.
