Happy70,

If you will go to Numrich Arms (Gun Parts Corp) you can find a schematic of a Smith & Wesson revolver with the parts identified.

What I don't understand is:
• You're taking an armorer's course about S&W revolvers, but you don't have any S&W revolvers to examine. Then why are you taking the course? Do you intend to work on S&W revolvers as a gunsmith? Without prior revolver experience?
• The course you're taking does not include any pictorial materials showing the inner workings of generic S&W revolvers? Who published this course?

Thanks for the reply. My course includes many firearms. I cannot afford to buy a firearm for each one. I do plan to work part-time in the future with a gunsmith with over 45 years experience. Also, I plan to to start with simple tasks at first and work my way up to more difficult tasks. I have a complete set of Jerry Kuhbhausen's books. Thanks!
