Casting Month Code:
A: January
B: February
C: March
D: April
E: May
F: June
G: July
H: August
"l": September
J: October
K: November
L: December
The Casting Code Letter was followed by digit(s) representing the day of the month, and the last digit designating the calendar year.
I think "L222" is December 22, 1972.
