Hi, Atticus,
Can you provide all the markings, barrel, underneath barrel, water table, breech, and also info on any engraving. Also condition, amount of bluing on barrels, condition of receiver finish and case hardening color.
Contrary to popular belief, few Parkers are actually rare. Ones in top condition bring nice prices, mainly because most were used and used hard, in the field and in duck blinds.
