What?
What part are you not understanding?

That is a stock, Airgun Designs 68 Automag, Level 7 Powerfeed.
That is what you got when you bought one for £289.
Then you needed an Airsystem or Co2 Setup.
They were built to run on air. The valve, was called the A.I.R, which stood for something like Advanced Integrated Regulator.
They could have various customisations.
You could buy splash annodised parts individually, including the 3.5 oz bottle, which fitted onto an anti liquid valve.
Eclipse sold these parts individually, but, they also sold complete guns, with all the parts and the Eclipse name on it.
So, your one..is an original Eclipse gun, which would be a custom marker.
