I have a Lyman I believe the 66 which was for the Model 94 Winchester on my Marlin 1895 cb. Lyman told me it wouldn't work. Marlin told me it wouldn't work. Gentlemen, it works. I centered the pin which holds the ejector in place on the mounting base and drilled and taped the base holes on either side and just below this pin hole. Milled the pin down just a little, so that it would not protrude and slid the sight into the mount. I now have exactly the same sight system on my 1957 Model 94 Winchester, my Navy Arms Model 92 Winchester clone, and the Marlin 1895 cb. Marlin and Lyman's logic was that there might not be enough windage on the sight for the 1895cb. If you mount the sight and still don't have enough windage on the sight. Drift the front one. That's what you would have to do on an express, only more so. I know, because I tried that one first.
