Thanks for the info, but that one will not work, this is the 82A ladder sight that origanally came with a target cap and a sporting cap that was used for hunting, the sporting cap provided a two position apeture when the ladder was in upright position the target peep was in sighting position. When the ladder was in the down position the sporting apeture was utilized, if I can't find guess I will have to make one. Thanks.
