I've got tons of quill-type 45D and 45A and I have a pair of Berthets handy which oddly came off a 69/70 Raleigh Pro. I'll check it out and report back.

Harvey: YUP! I just found a set of obviously (?) very late Berthets, marked R and L. These have evolved from "flats" to a hex shape (17 mm, of course). Even more shocking, they have 6 mm. allen key ends like real, modern pedals. Who would have Thunk It? And, they are NOS. No, they are real, not a vision from the Beer Fairy.

Harvey: I'm sorry to puncture the balloon, but Your Dedicated Reporter must tell you that the shafts on the Berthets are at least 1 cm shorter than on the ubiquitous rat-trap models. But you knew that. I didn't take 'em apart, this is just from holding up a Berthet next to several of the Lyotard. May not be true for quill-type Lyotards, but the box didn't reveal any of those. Of course, if you have a machinist friend...
