Hey Nick,
The only pedals for that bike are Lyotard Berthet. With your Christophe clips and straps. I have just such a pair (NOS) hung on the Stronglight cranks on my 1950 Locomotief. And I have another pair of Berthets; pre-owned, experienced, some "pitting" but they spin smoothly. I might have bought them from Hilary before I got the new ones. Or not. They're yours if you want 'em. If I lived in your neighborhood, I'd just bag 'em and toss 'em over your fence. Or into your bushes. Or however your stuff is usually delivered.
