Since the forum primarily focuses on Montblanc, information on side brands here is sparse. Collectors report that most collectors specialise in a few main brands like Montblanc, Pelikan or Namiki, and brands like Koh-I-Noor, Lamy or French bakelite pens are therefore barely documented. The Lamy mentioned is likely a Lamy 27 from the 1950s. For more detailed information the Penexchange forum is referred to, which covers a broader brand spectrum.
