I'm sure you have a few guys interested in your post.Most likely not a lot of Parkerphiles got to see the guns while they were there.The A1's and AA grades are usually the ones with engraving at the muzzles.altho' lower grades might have had it as a special order.I,for one,would like to know more about those guns.There was a man with the surname of "Lightner" who was a big collector of Parkers in Florida during the 60's-80's.He reprinted Parker catalogs,among others. I think he moved to California,or his son did when the father passed. He was always advertising for guns and high end "samuri swords".This is all from recollection of ads in the "Shotgun News" so I may have "recollected" in error as to particulars.
