These bookends are difficult because they all look so similar. The thin stem and flat leaf make me favor AVeM or Fratelli Toso. The ones Barbini and Archimede Seguso made c. 1960 had stems that were thickened on the end and leaves that stood out in greater relief from the body. These things make me think it was not by one of these companies.
I am not at all certain who did your pear, but my first guess is AVeM and the second is FT.
