Shimano 600 semi-platforms with steel washers bolted to a longer front toeclip bolt and a 1/2 x 1/8 steel bar tab bolted to the quill. Not light at all. Very easy fix gear pick up. And with slotted cleats like your ancestors rides very secure and efficient. (I took a pair of these off my good fix gear and put them on my best geared bike yesterday so I could use my best shoes. Took a while to remember "oh yeah, I don't have clipless" at stops, but what a ride!

That set-up has now done Cycle Oregon three times on the fix gear and on several different bikes >40,000 miles.

I hope some manufacturer starts making those pedals again. They were/are some of the better pedals ever made.
