The month and year should be stamped on the left side of the cylinder above the trigger. Look for the stamping “Made in West Germany” . Then in very small print you will see the date. I have to use a magnifier to read it. You should not have to remove the stock.
Take a couple photos of the anti-beartrap safety system if you rebuild it yourself.
