Eaton Breaker Date Code

[Bob]

I am trying to determine the date of manufacture of the subject breaker. Can anyone help me with that. I am not sure if the date code is shown. The face of the Eaton breaker has the following:

Eaton
Type BR260
Type C260
120/240 V -
Cu/Al
HACR Type
2 Pole J969
E7819 - T
LR43556 Disj

A guess would be 1978 week 19. Thanks for any guidance.
