In the lower gun can you see how the "bead line" on the bottom of the barrels flows into the line between the ball and the flat of the reciever? That is standard. On the top gun the beadline slopes down and away from the ball/flat line and misses it by probably an 1/8".
Also it appears to me that the barrel breech extends beyond the ball down low. That the barrel breech sticks out to the side, but just on the bottom.
