Does anyone know of a way to determine the date of manufacture for an IBM 3276 keyboard based on the part numbers on the internals? I am an idiot and lost track of which case goes with which on two units I was cleaning up. Most of the numbers are identical but one does have G322 while the other has G498. On the mounting plate there is one which has 317615 and it is 317626 on the other. The lower numbers are both on the same unit so I am thinking that is the older unit but would like to confirm if anyone has any insight. Thanks!
