This Goebel May Be 75?

I learned that the rarest and most valuable Goebels are the ones that are blue eyed. There are only a handful (if that) blue eyed pieces ever made. I also found out more recently from an online post, that the markings this Goebel has, represents the trademark used between 1923 (pre-production days) and 1939, not 1935-1949, as in the TM charts in my blog indicate.
