Looks like your post up the same lens twice if they’re actually different lenses there’ll be no difference that you’ll ever see
The one in your larger picture is newer production and should have a later serial number. The different typeface for the word "Kreuznach" is the key bit of evidence. But you want to see the rest of the labeling to see whether the lenses are in fact from the same generation optical design - for example, both Apo-Symmars - or whether one is a newer design - for example Apo-Symmar (older) vs Apo-Symmar L (newer).
Can't go wrong either way. They are superb lenses. Buy on condition and price.
