A WILLIAMSON PEN with pivoting "lever"
The pivoting "lever" was not a real pull lever but a small gold filled metal blade wich actuated over the pressure bar to depress the rubber sac with lateral movements ( instead of vertical ) . At least two pen makers used this kind of filling system : Williamson and Held ( both of them from Janesville ).
Thanks to my friend João Pavão Martins who worked on this nice photo.
