In my earlier post I said the dates were 1880 to 1896. My finger got in the way and I entered the wrong date. It should be 1883 to 1896 on the Model 1880 plier handle tool. The Model 1880 spoon handle tool was only available from 1880 to 1883 approximately. Sorry for the misinformation first time around. I hope this will clarify things.
Mike, nice tool. You have the 1880 4th issue made with Berdan cut-out and chisel. I have all of the tools and molds that Winchester made for all four of the 1876 calibers. I most often use my 1880 1st issue spoon handle tools when reloading these calibers. All the Winchester tools and molds work very well.
