This is an interesting question, The gun is made in Russia it comes in 3 different barrel lengths and different calibers. The manufacture was shipping them out of Russia until the government changed the law back in Feb 2011. Edgun has been trying to get permission to sell them out side of Russia but "RED TAPE" has blocked them and it looks like it's not going to happen in the near future. So if you live outside of Russia the only place that I know of is if someone wants to sell a used one and they can charge any price they want.

It all depends on who made the air rifle and the power plant that the rifle uses.
it all depends on the condition of the rifle.
in general 180 $ is the minimum for a reliable rifle.
What condition is it in..
Don't put as much air in the rifle. If you have a dial to set the power then use it. As you shot the power drops. You can dry fire some PCP air rifles.
An Air Rifle is either a BB rifle or a pellet rifle. It uses air or gas to propel the projectile.
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.
A sporter air rifle and what?
No
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.
50-200 USD
It all depends on the model and condition of the rifle.
