One of the hubs has a 74 and an 8. The other hub has a clear 9 where the 8 is on the other one. And the year appears to not be stamped well. I think I can maybe see another 74, the 4 seems lightly visible and maybe a 7, but maybe I'm seeing it because that's what I'm expecting. Was it common for not such a great stamp? I was also born on this year, so that's pretty cool
