Yes! I have the earlier steel ones which are original to the bike....but I'd like to treat it a little weigh saving!
Might see if the steel ones are worth selling!

Very intriguing....coffee hasn't quite kicked in yet....but....wouldn't a frame need to be a little bit specific for these pedals?

A more extreme version of Shimano's 600AX pedals, from memory it "added" 20mm to the frame size, because of the pedal body/platform being below the pedal axis. As per drawing, slow typist.

Funnily enough I just had a Eureka moment.....I clicked the link you posted
Coffee is now coming on strong.....I'm looking at my 29r from a 26 frame in a whole new light!
Hmmm I wonder

I've often looked at those....never really applied any grey cells to it.....of course! So less steerer less head tube and seatube and seatpost....that's weight right there...

Mine long gone, no GP4 tubs, I ran clinchers. Not French

Love this thread....my mind is now off on a different tangent today.
How did those pedals feel guinness? I assume toe/front wheel overlap is also reduced? Was the frame specific for the pedals? More chance of pedal strikes into and out if corners?
So many questions this is throwing up..

Pedals felt fine with Shimano shoes. Frame was a Standard 1982 Raleigh Road Ace, they were fitted with the 600AX groupset as standard. The pedals were physically thin, I never noticed or had any strikes. I can't remember about overlap, don't think it made any difference ie still had it.
