your model 310 was made between 1972-1975.
If it's not on the breech or barrel then it's a good chance there is none. For a time back in the 40's that Benjamin did not put any serial numbers on air guns. I also own one that has no serial number.
Most likely around late 1956 according to Crosman who owns Benjamin.
Well, honey, the Benjamin Model 310 air rifle was first introduced back in the 1940s, so you do the math on that one. If you've got one of these babies in your hands, you're holding a vintage piece of air gun history. Just remember, age ain't nothing but a number when it comes to a classic like the Benjamin 310.
The Benjamin model 312 was part of the 310 series of rifles that included 310, 312, and 317. They came in .177 and .22 caliber. Production started with the model 310 in 1940 and ended with the model 317 in 1969, the 312 fell somewhere in the middle of that time period

The Benjamin 310 series (310, 312, 317) were made between 1940-1969. My best guess it was made sometime during the 1950's they did not start putting on serial numbers until around 1957 so that should help narrow it down
