I don't know why the Heliar comes up whenever "soft-focus" is mentioned. In my experience, it ain't.

Well, there are Universal Heliars, which have the soft-focus adjustment. "Regular" Heliars, because they are fast, have shallow Dof wide open, and out-of-focus areas are rendered nicely.
But you're right, strictly speaking, NOT a soft focus lens.
My inquiries started when I discovered my 14" does not seem as sharp as my 11.75", but so far, that is subjectively based on GG view with a loupe.

black in a marvelous Compound shutter, just mounts on a Canham board. Heavy!
As Serge notes above, smoooooth. Have never closed it more than two stops so cannot judge behavior when closed down further.

Heliars are just to dam expensive anymore. I would like to have one, but they are not even worth it to "keep an eye out" for category.
I found this thread and thought this might be of interest.

So perhaps that lot of s/n was set aside for New York and they started selling them January 1,1904
I wish I had an early one. My 21cm, SN 3947984 is in a beautiful Compound shutter and is coated. I use it wide open mostly. It is sharp in the center and moves smoothly into the OOF areas, but I really wish I had a very early one because of their reported imaging qualities.
