ehhhmmmmm...
The Heliar was first, I believe. Then came the Dynar and the Oxyn. And then a Dynar-type lens was sold as Heliar, while the Heliar design lived on in the "Universal Heliar".
The Tele-Dynar seems to be "variable": Some are 4 in 3 like some Tele-Xenars, while others seem to be 5 in 3 - rather like a Dynar, but with different curvatures and spacing. I haven't used one myself, but I would assume the design criteria would be different from those of the Dynar/Heliar.
