Was this same Ultron design used on the Zeiss Icarex BM (or TM)?
It was almost the most expensive standard lens for the Icarex.

The Ultron is a really solid design. The f/2 50mm version used on the
Prominent is a most satisfactory lens, and this is identical to the Vitessa
optic. The lens was designed by the noted optical scientist, Tronnier, in
an unusual air-spaced double-Gauss configuration consisting of six
elements. USP 2,627,204.
