Of course, I can't be sure, but in context of the pile for sale...all beads were loose, not strung as Czech generally are, and along with these pinks were the opalescent lavendar, the greasy yellow, greasy peacock blue and some tiny aqua blue whitehearts - all beads that I used to order from Pierre Bovis, from the retired French factory, in the 80s when I used to work for General Bead. Not conclusive, of course, but to my eye they fit in with the rest of the group.
