Oh man, I though I recognized that gun. I hope one of the local boys pick that thing up, it will be sad to see it leave the area it was born in. And who ever said "those picture don't do it justice" is right, that machine is awesome.
Very rare gun. I had Dyna Bigun #2 which I had Jimmy make into a combo by adding a 34" unsingle. Unfortunately I never liked the unsingle. My gun did not have the rib extension over the receiver and no choke tubes. Good luck and up for a nice and unique gun.
