Which model. Benjamin made about 20 different models. Also state the condition of the rifle.
It all depends on the model. Which one are you asking about.
Unable to answer this question. No model number and no description of the problem.
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.....

The model 3100 & 3200 were manufactured between 1958-85. The 3100 is a BB pump rifle.
I am not familiar with this particular model (427) but I am familiar with Benjamin air rifle. If your problem is that there is on Scope rail to mount your scope then I know how to fix it. Crosman airguns owns Benjamin air guns. Crosman offers a special Benjamin barrel clamp that lets you mount a scope to it. See the link below
Model What? are you asking about an air rifle or something else. Do you have a model number? What condition is it in?
Benjamin made several different pump air rifles. Please specify which one you are asking about. The model number will most likely be on the barrel.
