There is no mystery here. I have collected Remington 1894 and 1900 for over 35 year's.And also gunsmithing work on them all that time. The forend look's normal on this gun. The large opening at the end of the forend is on both extractor and auto ejector gun's. The ejector forend has some more milling that must be done to the back sides and at the end to fit the ejector parts,hammers ,springs, etc. Some time's an extractor gun will have a forend iron on it that is milled out for the ejector parts. Maby one in 20 gun's. The extractor is normal on this gun,those two slots are on both extractor and auto ejector guns. Terry
