Not fooled - the battlefield revolver is a real Webley to my eyes, compare the hammers, the real one has the base of the firing pin showing as in all early photos in this post, the air pistol has no pin. The trigger on the battle field revolver is fully forward when in the uncocked position against its stop with no gap visible, the air pistol has a gap. The battle field has burred slots in some of the screws, the air pistol perfect, can't imagine they would go to this extent with individual parts, easy enough though to apply an old patina to the whole gun.

Still the air pistol looks pretty close to the real thing would like to see one in the flesh.
