You do indeed meet the standard of "an old time CFI". Quite a history there. Thanks.
It's more a matter of interesting trivia now, but at one point the rating on a flight instructor certificate would say "AIRPLANE". No single or multi, just airplane. The result was that CFIs would go out and get a multiengine rating on their commercial certificate and instantly become multiengine instructors. Then, with just enough knowledge to get the rating, they would proceed to kill themselves and their student by getting into situations that neither one of them could handle. So, in the early 70's, the FAA split the rating into what they called two "groups". Multiengine being one group and Single Engine being the other group within airplane. So we really have category, group, class, type, and model.
There was a period of a couple years where flight instructors could take their certificates to the FAA and with just an application be issued a new flight instructor certificate based on what they held at the time. After that, the process became more onerous.
Since accidents are the major driver of regulatory changes, the change must have been adequate since it hasn't changed since then.
If you ever get the chance to look at someone else's flight instructor certificate, just innocently ask them if there is an error on their certificate since the world "land" was left off. Chances are very good they have never even noticed that.
Years ago we would say that knowledge like this and a nickle will get you a cup of coffee, but that isn't the case nowadays. Coffee cost a lot more.
