With the recent influx of many "new-old-stock" (vintage) Lamy writing instruments into the market and the great experiences and rave reviews they are receiving, older Lamy fountain pens are going through a resurgence/revival of popularity and renewed interests of collectors and users alike. On the other hand, there are some of us out there that never quit being in love with them.
Among the most popular vintage Lamy models are the infamous Lamy 27, a predecessor to the Lamy 2000 (released in 1966) and the Lamy 99 which was produced when the 27 was discontinued, possibly due to the new Lamy 2000 taking over the 27's price-point niche. Less known and much less popular then and now are the Lamy 60 Series writing instruments that were released a few years later (1970?). This series of models included both cartridge-fillers (international size) and piston-fillers with both plastic capped models and those sporting a very durable steel cap. Pictured* below are the Lamy 66P (the "P" stood for "Patronen" meaning cartridge in German), the Lamy 67P (same as the 66P but with a steel cap), a Lamy 68 piston-filler, and two different iterations of the Lamy 69, also piston-fillers (same as the 68 except for the metal caps).
(Pictured from left: Lamy 66P, 67P, 68, and two different versions of the Lamy 69)
All of the Lamy Sixties Series came standard with exceptionally smooth steel/alloy nibs, and the notable "L" at the apex of the cap. At 5 1/4 inches in length (closed) with stainless-steel clips and chrome furniture, these resin pens fit perfectly into a medium-sized hand and continue to be a joy to use...
