Vintage ABAS Major air pistol no 1The serial number 261 is at the back of the main frame between the grips, and on the lower cocking lever near the trigger area.
On the right hand side of the cocking lever , it says Reg design 845425 AA Brown & Sons B’ham.
On the left side it says, ABAS prov pat.
On the front of the cylinder / barrel it says .177.
The front and rear sights are intact.
The chequered grips are in good condition with no cracks, the steel work has light rust as well as blueing.
I have fired a few pellets to try it. This took a bit of loading because the loading tap has been Brocken off.
(the thumb part) There is one small screw missing as shown on the photograph.
This part does not look difficult to make, as long as you had a drawing or one to copy from.
