Jamie,
It's very easy to become enamored with a Winchester model 21...happened to me at age 17 and stayed with me for 25 years until I obtained one. Obtain a copy of Ned Schwing's book, "Winchester's Finest The Model 21" and enjoy the reading. A word of caution if you do acquire the disposable income required for a 21.....it's like eating potato chips....ya can't stop with just one.
Welcome to the exhilarating and sometimes expensive world of side by side shotguns
