completely custom (hence the non-wavy chain stays)
I'm sure it's been said before in this thread (and I've probably got it from somewhere on here), but I've heard that straight-stayed Hetchins (Hetchinses?) are more valuable than wavy-stayed ones. The wavy stays became a kind of trademark and were produced much more.
They do seem more unusual for sure. I have however seen one real life wavy-stayed Hetchins and did think it looked pretty cool nowadays and agree that’s probably what many people associate them with.
This also has proper pencil thin seat stays which is apparently a good thing too
