For what it's worth, I did acquire an early 20's A.H. Fox AE 12 ga. with a broken ejector sear. One-owner gun before me but, no info on what could have caused it. Found a NOS sear for a couple of bucks (years ago) and gunsmith fitted it up for a few more bucks. Not sorry that I have ejectors in at least one of my Foxes. This gun does it all from ducks, dove, to pheasant. Good luck with the project!
