Hello from Adelaide. I'm a new member.
I have been a fountain pen user for 44 years. I have just started expanding my collection beyond the pragmatic to the indulgent by purchasing a second Waterman Laureat just for the sake of a different barrel colour. I have started collecting retro pens; mainly the cheaper but useful pens of my school years. I have just bought an unused Platignum Pressmatic dating from the late 1960s, still in the original package. What I remembered of a Pressmatic was the type with the rubber squeeze bladder on the filler. This one has a steel filler tube with a button on the top end which, I guess, you push down on to draw ink in to the filler. The button does not have much travel and doesn't seem to draw ink in when I press it, resulting in a limited writing time. Am I missing something here? Is there another action? I don't want to force anything. Is there a member who REmembers using one of these? I have attached a picture showing the mechanism.
