Let's start with the the toe-clips. These ones are made of steel and show a classic design (no identification mark, sorry).
They get attached to the pedal's body by means of a three bolt-and-nut system (that's nothing new under the sun, either). The most interesting feature is the three slotted adjusting system that gives a full centimetre of fore-aft tuning.
I'd dare to say that these toe-clips are the originals, probably sold as a pack with the pedals. If you look carefully at the middle picture you will notice a hollow triangular shape that exactly matches the pedals front contour.
