Hello Gaspare,
photograph #249206, the navy medical doctor ist such a (typical) case: BTW I do own this pic since the ebay sale
and with a lupe you can clearly see that there are two rings side by side. One is a small wedding ring, the other one is a kind of seal ring with two oval plates (one a little larger, one smaller) on top of each other.
No spectacular rings but clearly io see and to classify holding the pic in hands.
On the other hand, your pic #1 is a hard (impossible) case. I have two more, different pics of the same man
and in each one he is wearing another (!) ring and -how hard you try- in NO pic you can classify one of the rings.....
Regards,
PS.: The photograph should only show it�s the same person.
