Those look like they would have the same pattern as Look. I don't think the drilling has changed from the mid 80s. Delta or Keep. Mine wouldn't fit.
Futzing around with a trashed old pair of Diadoras, I think they'd work with one Look hole and one SPD hole on a dual style compatible shoe.
At this point, I'm totally happy with Keo's on the old bike. The Classique shoes make brand new look totally retro.
