A couple of quick points. The 1.25 and 2.5 infinity corrected are great
objectives if you are a pathologist, not many other researchers use them.
E. Leitz's NPL series of objectives were great! These Neo-Plans (NPL) were
great for fluorescence and other low light specimens that needed high
contrast. They just aren't as neccesary today.

The PlanApo 63X is one of the best lenses ever put together if it is in good
shape. If it has problems it has (I think) 18 elements in 16 groups. You
don't take this apart on your lunch hour.

In general it is a very mixed bag. If I wanted to resell things this would
be a good assortment. If I just wanted to use them, tons of problems.
