This is a German-made "Robot Luftwaffen (German Air Force) Model" by Otto Bening. The body back has the engraving "Luftwaffen-Eigentum" (German Air Force - Property). The serial number starts with F, indicating the Air Force. The exterior has significant damage, including paint and leather peeling. However, considering the age and intended use, this is probably reasonable. The viewfinder is somewhat difficult to see due to clouding and scratches. The horizontal viewfinder switching knob is broken. It can be switched with a toothpick, etc. The 75mm mask attachment hole is filled in. Surprisingly, the shutter works well and fired 12 shots. I didn't wind it fully because I'm worried about breaking the spring. There is significant clouding throughout the lens. The focusing helix and aperture work normally. Two magazines are included: one for release and one for winding. There is the number 11 on the back of the body and on the magazine, possibly a unit number. It is likely possible to take actual photos, but I haven't tested it. I recommend it as a collector's item for military fans. - Brand: Robot - Model: Robot II - Exterior Color: Black - Features: Rangefinder mechanism Thank you for viewing.
