The Crown Grade was a special order gun. You could order it any way you liked, (within reason). Most had ejectors and the Hunter One Trigger, which were an option. The Longrange/Wildfowl was an option also, I think for $5.00 more.
This Crown Grade you saw on GB has the re-inforced splinter, a nice feature which is designed as a shock absorber for the barrel loop.
The letter states it is a Longrange, most lower grades have the word Longrange or Wildfowl marked on the barrel lug. They were only made in 12 ga and on a Regular Frame. I believe most had 32" barrels and their claim to fame was taking ducks and geese up to 80 yards clean.
These guns were advertised as having a different choke for this type of longrange shooting, but the one I have doesn't show this, but has .042 contriction in both barrels, and is bored .729.
There are also some Longrange and Wildfowl that do not have 3" chambers, and most seem to be the Wildfowl.
