I've long been confused by S&W model numbers, so I grabbed my Standard Catalog and nerded out on a spreadsheet. The sheet shows each model's start date, each engineering revision "dash" date, and discontinuation date if there is one. If you grab a spreadsheet version, you can sort by whatever you like (frame size, chambering, et cetera), and there's also a PDF attachment to this post if you just want it the way it is.

LibreOffice/OpenOffice: http://ajlowry.net/guns/SWModelNumbers.ods
Mac/iOS Numbers: http://ajlowry.net/guns/SWModelNumbers.numbers
All the data comes from the Standard Catalog of Smith and Wesson, Fourth Edition, by Jim Supica and Richard Nahas. If you want to see some history on each model and what each engineering change entailed, it's all in the book.
