The 137 is part of the 130 series of Pistols. They included the 130, 132, and 137. Production started in 1946 with the 130 model and finished with the 137 in 1985. So yours would be made sometime from the late 70's to 85.
the 137 was made continually from 1946 to 1985 see the link below for more information on Benjamin. it looks like it was made in 1958
They were made from 1946 to 1985. If you gave me the serial number I might be able to give you a year.
Benjamin made this model from 1946 to 1985, but did not start serializing them until 1957. I also have a Benjamin Franklin that has no serial number. Before 1957 it is not possible to set an exact date. Just know it's OLD. The 137 is a .177 caliber pellet pistol the 132 is a .22 caliber pistol and the 130 is a BB pistol.

The model Benjamin 137 was made between 1946-1985. But you will need the Serial No to tell the exact date. In 1957 Benjamin used the serial number to establish the date. From 1946 to 1957 there are no records as to the date. See the link below for more information. BTW today Crosman air gun company owns the Benjamin line of products.
