Thanks for those links, Mike. They both are advertised as having "automatic
ejector", not ejector
s. This is usually a giveaway that the seller does not know the difference. When you enlarge the view of the second gun advertised, with the breech open, it looks like a one-piece extractor to me, though it is hard to tell definitively from a side view like that.
I read through Semmer's 16 pages, that he devotes to the Model 1889 in his book, and he makes no mention of the gun ever being made with ejectors. I am no expert on Remingtons, but I take him to be. I believe if 1889s had been offered with ejectors he would have said so.
Until I see proof I will stand by my belief that none were made. Thanks for the links, though, they are new sites to me.
All my best, SRH
