A list member has asked about the pedal shaft stampings, reminding me that "G" and "D" represent French threading, and "R" and "L" represent English/Italian. So I looked carefully at all the Berthet shafts I have (including a pair I'm keeping). And the result is:
R: 3 shafts L: 2 shafts blank: 1 shaft (Left).
All 6 shafts are very close to the same diameter, just under 14 mm on my lovely swiss plastic dial-vernier. Go figure, I trusted the stamping, too... Viva La France!

I have two pair of "good" Lyotard Berthet platform pedals I could part with, for folks trying to complete French restorations with the most common upgrade of the era.
By "Good" I mean that they have spots of rust on the end caps, etc, but ought to clean up decently with a little elbow grease.
By "French" I mean that I just checked the threads, and they are about 0.3 mm smaller diameter my reference English Suntour Superbes, so I assume French threading. BUT, they are long-thread shafts, meaning the ones intended for cotterless aluminum cranks (Remember the difference, when these were less common than the short shafts for steel cranks?).
So, if you want pedals that make the bike look right, these will do fine. If you want to ride hard, you better not use English crank arms if your weight or strenght are large.
But, let's be honest: most of us ride with off-topic pedals, and just put on the authentic ones for display.* These will cinch up and look just fine. No toe clips or straps. Tell me the price is absurd and offer something in trade, or
$28/pr, shipped in US.
