I guess I'm still running against the wind, but after 50 years of shooting double guns, I still prefer ejectors.
Your question was concerning OLD ENGLISH guns with ejectors. I have no first-hand knowledge of this, not owning any old English ejector guns. However, given the penchant of owners of them to play the unreliability card, maybe they know something I don't, that is, that old English guns had unreliable ejector systems. I think more likely, though, is the idea that the opponents of ejectors just don't like them kicking their shells out on the ground, and haven't learned the childishly simple task of catching them as they do eject. Anyone who can use double triggers successfully certainly possesses the dexterity to catch two empties as they are ejected, right into your hand.
If, indeed, there was/is a reliability issue with ejectors in old English guns it was certainly solved by most current makers of good double guns. Ejector reliability just is not an issue with Perazzi, Beretta, Kreighoff,Kolar,and multitudes of other doubles built in the last 40 years or so.
