I have used double gund all of my life. However I inherited a well preserved Winchester model 1897 shotgun made in 1905 from my 95 year dad. It is a take down model and for the life of me I cannot seem to get it apart into its two componants. Has anyone had experience with this type of shotgun? He also gve me a beautiful L. C. Smith 20 ga. gun with ejectors. I can hardly wait to try it out.
