Did I Catch a Niner in There?

8 line Hamilton Calendar Figures, style No. 6309

According to the 1938 Hamilton specimen, “All calendar figures in any one size and style are made up in uniform size blocks. A set includes figures 1 to 31, fractions, and seven blanks.” The price in 1938 for an 8 line Calendar Set (as just described) was $13. All of the figures and fractions are present in my font, sadly I am missing the seven blanks.
