Vintage Minolta 16 Model II Chiyoda Kogaku Japan Camera. To be completely servicable it should include the original supplementary lenses. One negative lens allows focusing at infinitive at full aperture. Two positive lensrs for close focusing. Lens Rokkor 1:2.8 F=22mm. These are from my grandfathers collection. They have been looked at but not repaired or made to be in working order. They may need a simple battery, or adjustment. However, they have been in the family for decades and stored in air conditioning to keep the integrity of the cameras.
