an interesting hand made air rifle

[T 20]

I cannot see what the detent latch is supposed to do. it does not locate against any thing I can see. Then again I did not see a grassy knoll for the 2nd shooter.

I can't see what the piston is meant to do as the cocking lever slot extends from the breach to the trigger with no compression chamber.

I thought the second shooter was in the car park behind the grassy knoll ?
