As you can see from the photo, there are several things on the bottom of the bottle. I think the most significant is the bottom one which reads: "22 17A 72". Incidentally, the top line reads: "16222" and "LOU-02", with some kind of a trademark in between that I can't make out.
As others have pointed out....1972 appears to be the distillation year, which places the bottling around 1977. That would be in line with ACDetroits comment about the cap being TE steel cap.
