Robot II industrial camera in excellent condition. everything works perfectly. the included attachment seems to be a lens for either borescopic or endoscopic use. the mount is however still the regular Robot mount so it will take normal lenses as well. The spring is quite special. normally a double spring version will give you 40 shots. this one however is even taller than a regular 'double spring' version and i get 52 shots on a full winding of the camera. a very rare robot camera for the serious collector or for those who want to shoot of 52 shots in rapid succession using a normal lens.
