Post subject:  SDR issue date

All the SDRs listed at TAC appear to be referenced in a newletter; can the newsletter date be considered the date of issuance for a particular SDR? Were plans sold after the issuance of an SDR updated to include the SDR?

I would say yes even though I haven't verified all of them. I know the elevator tab strap was incorporated into the drawings (517L revision A, 20 Jan 1969). I don't know when it came out in the news letter.

Yes. And the drawings were either updated via a revision as Jeff pointed out, or in some cases another drawing was issued such as a -A, -B etc.
