Actually I think it was available up into the mid to late 70s...

80/88, and it was colored Red...


80/87 avgas was (is) NOT unleaded. It just has less lead content than
even
"low lead" 100 (100LL) and WAY less than "conventional" 100 octane (which
you never see anymore).

The specification for red 80 octane did include the option for no lead to be
added. We had it at the airport until about a year ago.
