It should have a "engineering number" on the side.
It'll probably be like D5TE, D8TE, or D9TE. Maybe something else. The first Letter represents the decade. C for the 60's, D for the 70's, E for the 80's, and F for the 90's. The second spot tells the year of the decade. The third tells what application the part was engineered for. The fourth tells what group the part is for.
There is usually a dash and two digits. This is usually for an update in design.
There are also date codes, I have to get the book out to read those, if you get em for me, I'll try to decipher them.
