Here's an oddity
 

Here's one that surely can't happen all too often.... especially this
many years after manufacture...

I have two old 90mm Schneider Angulons in my small collection of
lenses.. with sequential serial numbers... one straight after the
other. I obtained these at different times from different sources.

I guess stats would state that this is as likely as any other
combination, but it's quite fun all the same :)

Anyone else have similar oddities?
