From the serial number. There are various references that list ranges of serial numbers for different years.
The 22 9 shot HR (High Standard) pistol with serial number P480 was manufactured in 1971. High Standard produced various models of pistols during this time, and the serial number system they used helps identify the year of production.
I'm sorry, but I don't have access to specific manufacturing dates for firearms based on serial numbers. To find the manufacture date of an HR 929 pistol with the serial number AE 2346, I recommend contacting the manufacturer or checking with a firearm expert or database that specializes in historical firearm information.

The serial model number for the HR Plainsman 22 model 865 is typically found on the frame of the firearm, often located on the underside of the receiver or near the trigger guard.

If you're having difficulty locating it, consulting the manufacturer's manual or contacting the manufacturer directly may provide additional guidance.
