Anyone ever heard of a Gundlach Manhattan Equal Diffusion lens? This example is an 18" f/4 lens and the seller claims it's a soft focus lens which sounds plausible given the name.

It looks like it dates from the 20's at the end of the use of the Gundlach Manhattan name. The barrel looks like it might be aluminum and I don't think I've ever seen similar leatherette (or leather) covering. Any idea on the optical formula? Gundlach has a line of Hyperion Diffusion lenses listed in a catalog from 1910/1920 (at Camera Eccentric), so maybe this is the same design It mentions that the Hyperions are convertible, so maybe it's similar to a Verito design. The name sounds a bit like they were competing with Pinkham and Smith. Anyone ever use an Equal Diffusion or a Hyperion?
