I believe it is from the 1940s. The box is complete but does show some wear as well. It comes with the manual as well as instructions for seal replacement. I pumped it 4 times an fired a pellet and it worked strong. The item "Benjamin Target Pistol model 137 pump pellet pistol WORKS GREAT withBox & Manual" is in sale since Sunday, July 11, 2021.
