I found these on the internet search
This one with its ROHS compliance is not vintage I'm sure.
The top row of this one was called "custom inductors that I had made for me."
The one in my pedal looks to have had the shiny metal halo ring on the top of it at one time. Look at the edge nearest in the photo and you'll see an indentation of a circular something. The color of the top is lighter inside that missing whatever and darker around the outside of it.
