I am no gunsmith, barely a hobbyist who likes to mess with old guns sometimes. I am usually working on Model 1873 and 1892 Winchesters. My friend asked me how to take apart his Model 61 .22 Winchester. After looking it over, I am stumped. Is there a quick easy description of takedown procedure someone could give, or perhaps a website with the info? My web searches all come up empty, including this site. If I need to have him buy a book, what do you recommend?
