I should have also added a few more things with the pictures: first, the 3 pins on the back of the receiver, veiwed from the top are cocking indicators, they retract once the barrel is fired. The front trigger fires the right barrel, the back trigger fires the left barrel and then the front trigger pulled again fires the bottom barrel. The barrels are 26 3/4" choked, cyclinder, skeet and full. The gun weighs 6lbs 9oz and is very well balanced & lively.

Can anyone tell me when they think it might have been made? I haven't been able to find any dates on the gun.

Thanks for all the info so far.
