Since I start collecting pens (my first pen was P25 BP), I have always kept stainless steel Parker ballpoint pens. Now I decide to complete a Flighter Ballpoint pen collection. So far I have, L-R: Classic/75/180 - this came as well with corespondent fountain pen line 61/65 Jotter - mid 2000 line 15 Vector 25 IM Obviously Flighter line start with the iconic Parker 51: Here is a bit of history of Flighter pens and how is started: http://www.richardspens.com/ref/design/flighters.htm To complete my collection I have identified the following models: 45/ 50 - Falcon/ 75 -cap action/ 95/ Arrow/ Inflection/ Insignia/ Sonnet. Also Stainless Steel Frontier, but this will be only half Flighter... If I'm missing something, or is there any wrong info just let me know.
