|  nfortunately the filling system had proven complicated from a manufacturing point of view and the manufacturing cost was high. While the filling system had no moving parts it still required the user to sometimes wipe down the teflon tube filler, and furthermore, since most users didn't want to bother with keeping their writing instrument clean, they seldom had it washed or flushed clean of ink. Hence it eventually clogged. Also The Parker "45" could be filled from a bottle if one used a converter but, then again, the nib needed a good wipe after the filling.
 With the Parker "VP" Parker tried another approach. A new style of converter was manufactured. As opposed to the standard converters this one ended in a long, thin tube that the user would insert into the bottle, compress the sac inside the filler and then replacing the filler into the pen. It was made from a clear plastic and contained a thin breather tube inside. It looked a lot like the Parker "51" aerometric filler, but was not a true aerometric. It sounded like a nice, simple solution but the thin, plastic tube that was to forcibly be inserted into the back of the ink collector was very prone to breakage and the Parker after services was instantly overwhelmed with broken Parker "VP"s.

 It was priced at $10, which made it a medium priced pen below the Parker 51, the standard model cost $ and the Parker "61" which cost $, but over the Parker "45", priced at $5. The different nibs had a number imprinted on them under the Parker name, denoting the style.      61: Needle Point
