The weird thing about this pen is the filling system. When the blind cap is removed, a plastic button is exposed. When the barrel is removed, a plastic sac is revealed which is shellacked to the button on one end and to the section on the other. A breather tube is shown here throught the transparent sac. The pen fills as a button filler. Short pressings of the button create vacuum for the ink to be sucked in through the breather tube. The stiffness (or lack of it) of the sac provides some resistance to the button.
The pen is very reminiscent of the (vintage 30s) Wahl Bantam (see here fore details of this nice little pen). The advantage of this pen is that the trnasparent plastic button allows to check the level of ink. Of course some Bantams were doing the same think with striped transparent barrels.
The "greek" E is inscribed on the section and the imprint on the body hint that this is a 50s pen (also the plastic).
Any information about this model would be very much appreciated.
