Interestingly enough I have read that Remington "usually" stamped an E on the barrel tubes with the grade to indicate an ejector gun (mine has no E). However they were reported to be inconsistent with that practice. One fellow on the Doublegun site reports having seen two other 1894 extractor guns with ejector forends and no E stamping. Here is another one. I am getting a sense some extractor model 1894's may have left the factory with ejector forend iron.
