At the 9:00 O'clock and 3:00 O'clock positions. The stamps will be on the flat area around the dimple. A letter will be the month then a single digit for the day of the month. According to this reference there is nothing for the year. If you can't find this I'll see if I can come up with a photo for you. John

I just read a little further in the reference I'm using. I was wrong about the year being stamped into the housing.
