This version introduced in 1936 is a lightweight model made from “Elektron” alloy. Although the alloy made for an easy to carry binocular, it did not prove stable under marine conditions and, for this reason, during WW II Hensoldt Dialyts saw little use by the German navy. This example is extremely comfortable to carry and a pleasure to hold and point feeling a little like the Barr & Stroud civilian Porro II’s. Optically the image seems bright for uncoated optics and is sharp to about 70-75% from center. Build quality of this between-the-wars civilian model, however, is uneven. Positively, the prism assembly is very solid and secure in the binocular housing and should withstand rough usage as well or better than many Porro I designs and certainly better than most Porro II’s. Negatively, many examples are seen with the texturized hard rubber coverings either loose, cracking or absent, and the painted finish is often chipped and flaked off.
