If you want an estimate of value then you will have to give more information about the condition of the rifle. If I asked you how much is a 57 Chevy worth, you would ask. "What condition is it in, does it still work?" its the same with any antique. You will have to give it some sort of rating like Poor, Fair, Good, Very Good or Excellent. State if it still holds air and does it still fire. All of this determines the current value
Which model. Benjamin made about 20 different models. Also state the condition of the rifle.
Benjamin made a model 1300 air pistol not a air rifle. It would be worth between $130-$155 in VG shape They were made between 1959-1964 They did make a 3100 air rifle... If you have a 1300 rifle then I do not know the value.....
Sterling of England was purchased by Benjamin air gun co in 1994 (After Crosman purchased Benjamin) The Sterling line was discontinued. The HR81 came in calibers of .177, 20 and .22. if fired at a speed of 700/600 FPS. Unfortunately you did not state the current condition of the rifle so I can not give you an estimate of value.
