without any further treatment after removing from the boards,
one has been desoldered from a lead-free soldered board and the other
from a
leaded-solder board. Particularly looking at the top pin of each
capacitor
would anyone care to comment?
You asked before.
I'm not clear what it's supposed to show. It's not as clear as it could be

I went back to the original unscaled image , although 2 cuts, they are from
the same pic taken at the same time with the same illumination

The lower lead free de-soldered cap lead and the upper a control from an
older board. Proper silvery sheen, mostly, to the old one, brighter than the
background graph paper, and totally dusty light grey for the lead-free ,
tin-pest ? desoldered one.
