Barrels look pretty thick. I don't know what the chokes are. I'm thinking about having it bored mod and skeet, which will work for clays I think. Both muzzles look the same size. It's probably Full and Full. Don't know. A dime sets the same in both and doesn't fall in. All of my other old doubles are Full and Mod and I shoot modern shells in them. Here I'll reload my own, but first I'll buy some Polywad or RST's. Nor do I know the length of the chamber. If it is short I'll just shoot 2.5 inch shells in it. Unique. That's neat.
Looks like the bead has been pounded down flatish. I may replace it with ivory. First I have to have the cocking mechanism repaired. Has a little too much drop maybe, but the LOP seems perfect. Haven't measured it yet. I just brought it home.
Paid $999 for the old Parker. I think I did okay. No chips or serious dings, nice bore a little case color, nice damascus colors, looks like plenty of steel in the barrels. These Parker shotguns are very neat, aren't they!
