I have a pair of Lyotard Berthet pedals for sale that are in very good condition . I actually think the pedal cage is NOS, though I cannot remember for sure. They have very slight spotting of rust on them, but no pitting. The spindles were replaced with other Lyotard spindles. The pedals turn smoothly and evenly. They require a 17 mm wrench for putitng on a crank or one could use a hex wrench. They are English threaded.
$40 including mailing within the USA.
If you want pictures, I have some.
Thank you.
Cheers.
