Working on a resin DL-44 and trying to find what the main body of the Hensoldt Wetzlar Dialyt 3x is made out of. I have hunted the DL -44 threads but can not find the information on this any photos appear different. I look forward the your help to get right
The main body is blued steel. Dry blued steel is a very dark grey with a slight hint of metallic blue. How much blue (or even purple) depends on the specific steel alloy. Blued steel is always oiled to protect it further and that makes it darker and glossy.
I would say that gloss black paint would make a simple approximation to the finish.
The rings around the front and back lenses, as well as the knob on top are brass, painted satin black and somewhat worn around the edges.
