Winchester Model 97 Pump Shotgun
Winchester Model 97 Shotgun
Bob Dunlap is a renowned expert on most of today and yesterdays important and obscure firearms. He has been a warranty station for most manufacturers, both large and small. He understands the design, function, and repair of firearms in general, and certainly the gun that was John Brownings first pump shotgun, and a runaway favorite of the Cowboy Action crowd, the 97 Winchester. Does not cover exactly the Norinco replicas, but most of the information is applicable. John Moses Browning is Bobs hero, and with good reason.
If you want the quick course on how to get the World Champions Favorite Cowboy Shotgun apart, back together, and operating as intended, then this course is for you (if you want the long course, look into our basic 108 hour Professional Gunsmith Course.)
Among the items covered are:

If you pay attention to Bobs explanation of how things (parts) work, work together, and their relationship to one another, you will have no trouble figuring how yours comes apart
