take a look at gunbroker item # 246458849. this otherwise nice parker vh shotgun appears to have had it's receiver put through the fires of hell? some idiot appears to have attempted to restore the receiver case colors via a high heat, bone charcoal process, that among other questionable practices, requires that the receiver metal be heated to 1400 or more degrees fahrenheit! obviously, the original factory heat treating of the receiver metal has been forever destroyed! hopefully, the maniac who did this work got lucky and was able to correctly retemper the metal somewhat, so the receiver does not crack on firing or worse...madness...
