Greetings. I just opened up a couple of Pilot Elites for cleaning. I have 2 completely different converters! I can identify the Con-20, but does anyone have a clue about the other 2? Are they knockoff Con-20s? The top converter is inscribed PRESS HERE PILOT 9007 on the mechanism that depresses to release the liquid. It has threads which make it slightly longer than the Con-20. The middle converter has the "PRESS HERE" but no "PILOT MADE IN JAPAN". The middle one also seems as if its insert is clear, rather than the blue of the Con-20. The Con-20 (or what I believe is a Con-20) is on the bottom. The mystery converters are from Pilot Elite with gold plated nibs.
