Picked this up at a small gun show in town here today. Don't know jack about Parkers, but it seemed to fit me very well and looked to be in decent condition. By the serial number it dates it at 1899. Has
# 2 Vulcan steel barrels and a number 2 frame. 12 ga 30 in with .033" const in the RH and .039" const in the Lh. I think it might be an 0 grade? Lemme know what I've got. Thanks John
