Es gab zu der Zeit viele Hersteller die ihre top of the line Kurbeln als Zweiarm Varianten ausgeführt haben zum Beispil Chater Lea, Diamant, magistroni, Dürkopp oder Smutny, da diese Kurbel von eienem Österrreichischen Sammler stammt vermuten wir dass sie von Smutny oder einem anderem össtereichischem Hersteller stammt
