I remember Dean's two barrel set, wonderful gun. A two barrel .410 set was floating around Virginia shows about 25 or 30 years ago and I would not bite the bullet. I also would not bite the bullet on $4000 plus average .410 guns over the years. The 30" gun held my attention. "Hooded comb" probably refers to the fluted comb in the picture of the pistol grip gun that is absent in the straight grip gun.
