Serial numbers were not required before 1968. Check the barrel and receiver.
The Davis P380 typically has the serial number located on the grip, but it may also be found on the frame of the firearm, usually on the left side or under the slide. Additionally, some models may have the serial number marked on the barrel. It's important to check the manufacturer's specifications or consult a gunsmith for exact locations.

Hallet Davis & Co. started with serial 163000 in 1938. Your serial 163344, then, would have been produced fairly early on in the year. As a pre-1960 build, we can also assume this is a grand piano; Hallet Davis did not start producing uprights until after 1960.
