	* Normally, the labeling is “rolled on” automatically as the sheet is manufactured and is aligned with the edges of the sheet. According to sources at ALCOA the non-aligned labeling on 2-2-V-1 suggests that it was applied by hand-stamping which may indicate that it was part of a very early and small production run.
