So, both spoons are from Geneva. The spoon with PA makers mark is from Paul Aberle, 1825-1888, in Geneva since 1847.
On the 3eme mark: Geneva was one of the few Swiss towns with a system to control the fineness of silver alloys used. The marking system from 1815 to 1881 was as follows:
1st standard (950) an eagle head
2nd standard (875) a horse head
3rd standard (800) a lions head.
However, also common was just the makers initials with the standard use. This is the case for your two spoons.
