The scope of the black color also made a small number of preparations!

Genuine article ZFG42 scope was manufactured with brass.
It is rather color near "bronze".
It imagined that what was manufactured by brass "was faded" by many years past.
(The material is a zinc alloy.)
Magnification is not on a lens. It is a transparent acrylics plate.
However, the appearance of this ZFG42 replica seems to be a genuine article!
