Jim, presumming the guns you listed are 12 ga. #1 looks correct, #2 looks correct. #3 looks correct for the year, the "E" stands for ejector, does it have ejectors?. The 00 is a grade in itself, where are these stamped? Looks like it might be a marriage of two different guns. #4 sounds like it is a Quality 2 with the scroll work on the sideplates and made in Fulton, N.Y.. #3 would be a Grade 2 with the woodcock and the ducks on the sideplates.
