as Bruno Taut mentioned that the "ornamental design" was invented designed by Shigeki Chiba 千葉茂樹 USD260658 and JP 586163 . however, the Justus original mechanism could be invented by Shikichi Yanagita 柳田清吉 as he filed the patent US4347011, "Fountain pen equipped with a resiliency adjustment device" on Nov 1979. it also referenced to the Japan patents S55-69496, S55-114592, S55-114593, S55-114594, S56-17172, S61-13097.

the new Justus95 has two finishes, the NB, "net black" or barleycorn and SB, "stripe black". it is larger than the original FJ-1000R-B released in 1979. the Justus95 can be filled with con-70 converter
