Those SOs are gorgeous.
I made an offer on a pristine Made-in-Canada set available locally just this week. It's the full, 19-piece set up to 1-5/8" (with one small wrench missing), but I doubt I'll get them. They're a steal at the guy's ask, but I just don't have the spare $ right now & have no need of the large sizes. Still, I'm very tempted...
