Neat wing shooting sighting aid

[NRA life member, Pope And Young Member]

It's been a year since the last time was on the forum and here I am again with another Parker shotgun that I have came into acquiring. This one is a DH in 12 Ga with Damascus barrels. The first oddity is the fact it doesn't have a safety. I called Bud and he explained it was a live pigeon gun and gave me lots of neat info on the gun. I wanted to show some pics of the front sighting, I'm guessing the original owner had these installed to help with wing shooting. I figured some of you guys may have seen these before but I'm just putting them out here for other's who haven't.
