Hello Steven,
I'm an admirer of Heliar imaging subtleties, let me tell you what I learned until now.
Beyond excellent link provided by Mr Fromm perhaps you know this:

My most desired glass is Universal Heliar 36 (for 8x10) , as you may see this glass was born in 1926 and it takes the 1902 design, but adding a difusion ring to adjust softness, this ring displaces the inner element out of its "ideal" position in order to add an adjustable amount of spherical aberration.
The term "Universal" comes from the 1926 aesthetical canon, this lens can be a general sharp taking lens, or an adjustable soft lens, so a Pro of the era had two lenses in one. The "kind of softness" it delivers it is particularly pleasing (to me), this comes from the "shape of the difusion", here in this shot (zooming in) you can see that some light from distant bright points is directed to the center of the image, this tells about the "nature" of the difusion, in the same way that there are different kinds of Bokeh, here difusion is set at 2.5:

Beyond difusion, of course the Heliar Bokeh nature is also impressive, IMHO japanese photographers are the most proficient to evaluate that, japanese imaging subculture about Bokeh is very strong, they are able speak hours long about bokeh subtleties of a glass. And it is not by chance that Heliars were highly regarded in Japan.
Shutter:
In the far past, with low speed emulsions of the era, shutters were not "mandatory" at all, still old camera (bulb...) shutters for barrels could be used.
As Told by Mr Gales the straight way is a Sinar shutter, but the 36cm it also can be DIY mounted in a Compound #5, I don't know if the #5 limits a bit max aperture.
Another DIY way I consider is to take a Graflex Speed Graphic shutter and to mount it in the rear of the front standard.
