Ray, I agree with randy, at first glance it looks just like the 150 gr. Umbrella Point, although, if authentic, I can’t explain the dark brown color of the lower part. There seems to be some black spots on the copper and corrosion on the emerging lead; maybe it was once cleaned with a product that oxidized the tin plating?
For what it’s worth, this loading was announced by Remington Arms-Union Metallic Cartridge Co. in 1913 and was to be on the market about September 1st. It was first listed in the 1915-16 catalogue and last listed in the 1918-19 edition. By 1920, it was considered to be a bullet easily deflected, innacurate and prone to cause feeding problems in the Model 1895, and thus dropped in favour of the then new Bronze Point Expanding.
