... those 30-ish style stems -- nothing compares today.
100% agree.
For a while, every pipe model (premium brand ones, anyway) that could "handle" the style was swan-neck-ified.
Even the leetle ones.
Here's a CK. It'll fit in a shirt pocket:
Many of the shapes/models still exist that were once swannies, but the elegance is gone.
Here's the same brand, finish, and model eighty years later:
Why did the elegant look disappear?
As a stem maker myself, I have zero doubt it was the usual reason humans (in the final analysis) do
anything --- Money
Not because a swanny stem takes more material, but because it takes more labor. They are a right royal pain in the ass to make, and there's no way to get around it. The stem has to be made twice. Shaped, then bent, then shaped some more
AFTER bending.
Meaning pipe company owners and cost accountants were glad to see the fashion disappear in the rearview mirror.
Pipe collectors, not so much...
