Still a few left, but numbers are getting thin. NASDS instructor # 867. A comment about using SSI numbers for certification numbers; I have a few records from 1967 and the earliest number I can find is #1681. I just happen to know this fellow and he said it isn't any part of his SSI number. Unless John Gaffney changed the policy I think he started at 1000 and went up from there. Oh, that John!
