Mjac, I just went to the Gun Parts site and punched in the item number for the vernier sight, they say that they are out. Sorry I did not do that before I got your hopes up. That sight used to be sold by T/C, I read somewhere that Lyman made them. It is more of a target sight then a hunting sight. There is another tang mounted peep that T/C still sells, it is really better for a hunting gun and you don't have to swap to a taller front sight. They sell on ebay most of the time, Gun Parts may have them too, I did not check. Sorry about the outdated info that I gave.
