Continuing to work both sides of the English Channel here...
My PX-10E ('74-ish) has a PIVO stem. I thought AVA stems (which no one has anything nice to say about) were standard fit on these machines. Since everything on this machine seems 100 per cent original I would be surprised if the original owner swaped stems. Anyone else out there have or see a PX-10 with this??
