I pulled O'Connors "Shotgun Book" out of the closet to see what he had to say about this gun. On P 33 he tells about the crappy trigger that he had replaced by Miller, in Pennsylvania. Apparently this gun was the 2nd Arizaga he ordered, the 1st being a 28 bore, for which he paid 160 bucks. He seemed pretty happy with this one, except for the checkering. He had Al Biesen rechecker it..Wonder where IT is? The 20 came to him in 1962 at a price of around 250 bucks with two sets of bbls. He mentions that after the Miller was installed, he had about 500 bucks in it..I should be so lucky...He had nothing good to say about Spanish single triggers...
