Well, I picked up another model 90 yesterday. This one intrigues me... its a 410/410. The thing that gets me is it has much more extensive checkering than my other 90's, but it also has a raised vent rib sitting on top of the barrel!! I had never seen one and just had to have it. For the price, I know I did well. I paid about 1/3 what it books for. This makes my fourth 90. Now the search continues for the 22 hornet/410!!
