Oh yeah baby, you can be James Bond and Weegee all at the same time with this gem!
After a bit of digging I discovered it’s DORYU 2-16 with Cine-Nikkor 25mm F1.4 lens.

" This camera is a serious camera for the police, and not a toy. It is a pistol camera DORYU 2-16 famous as rare and valuable camera. The DORYU 2-16 has the same C mount as the 16mm movie camera. A Cine-Nikkor 25mm F1.4 lens was able to be mounted in the DORYU 2-16 pistol camera. You can find the small lens for GOLDECK 16 on the table."

This is something I’d buy if I had that chance.
The site has some impressive Nikon gear on it, I like those S Motor bodies a lot! I love Nikon cameras, go check it out.
