To determine the age of a model automatic pistol chambered in .635 caliber, you'd typically need the specific manufacturer's details, including the model number and year of production. Many manufacturers also have serial number databases that can help establish the year of manufacture. If you have the model and serial number, I recommend checking with the manufacturer or a firearms expert for accurate dating.
