To get an estimate of value you will have to state the condition of the rifle and give the SN#. There are 5 different series of this rifle.
In poor condition it is worth $30 in Like new condition it is worth $150
A Webley & Scott Junior is worth: 100%=$150, 90%=$110, 60%=$80 Mfg late 1940s to late 1960s.
Without more information about the condition of the pistol, it is not possible to give you an estimate of value.
I am a little confused by your question. Do you mean Webley air rifle. I know that Wembly makes scopes but I am unaware that they make air rifles. If you mean Webley then I need to know the condition and the model of the rifle to give an estimate of value.
