This is fantastic, your tenacity is inspiring.
My Olmo that is on the registry has Mafac Dural forge like yours and seems to have come with them.
It came with the GS RD with the barrel adjuster and I assume FD and shift levers to match, I knew this is finicky through this time period so I will check my parts against
iab's info but have always assumed they were original and correct.
I also believe at this point in the game for many different reasons you have to be willing to take some poetic license, maybe short term, maybe longer if you want to get a bike on the road to stay inspired for the long run.
