3. ↑ Andrew Gibson. O_4 is the only date marking found.
4. ↑ Andrew Gibson. After discussion with Rick Soller at Springfield in 2006, it appears that the 1934 mold set was re-worked. The mold dates were blotted out, and re-engraved as 38, and the lettering was reduced in size. The would be the [130] with the blotout. It is unclear whether new molds were made or not, which would be the [050] without the blotout.
5. ↑ Andrew Gibson. 43:: is the only date code found on this style.
6. ↑ Andrew Gibson. Copies of Armstrong blueprints from Richard Wentzel show the mold for the CD 160, and they have a hand written "Obsolete 9/19/57" across one corner.
