The instruction manual from S&W that is provided with a gun is not a good reference for taking apart a 3rd gen pistol, especially if you want to go beyond the most basic form of disassembly called field stripping.
However... the 3rd gen pistol is not something to be messed around with unless you really know how the internal lockwork functions. It is one of the most complicated in terms of gun timing and relationship of parts.
Having said that... there are various videos on YouTube that are quite good for learning how to take down a 3rd generation S&W pistol.

The Wesson part of Smith and Wesson.
S was not part of the Model 36 sn convention.
Aftermarket part
The Smith & Wesson Model 29-3, with serial number AVC 6797, was produced in 1987. The Model 29-3 is part of the renowned .44 Magnum revolver series and was manufactured during a period when Smith & Wesson was making various updates and improvements to their revolver line. For more precise dating, specific reference materials or production records from Smith & Wesson can be consulted.
The Smith & Wesson Model 13-3 revolver was produced from 1982 to 1988. This model is part of the K-frame series and is chambered for the .357 Magnum cartridge. It features a square butt design and is known for its durability and reliability in law enforcement and personal defense.
The condition of the gun plays a major part. For this shotgun, in 95% condition, the average is around $350.
The value of a 32.20 Smith and Wesson 1914 revolver 6 shot with a sawed off barrel depends on the condition and the model number. Model from this year are valued between 400.00 and 650.00 but the sawed off barrel greatly reduces value.
Not a user-serviceable part. You need to see a gunsmith.
That was part of a special run of adjustable sight Model 60 revolvers made in 1986 (adj sights were not cataloged on this model until the Model 60-10 in 1996). Value in excellent condition would be around $400.
Part of the serial number. CHeck the butt.
The 469 is very similar to the 59, 459, and 669. Gun Digest publishes an excellent series on Firearms Assembly and Disassembly and the Part 1 Automaic Pistols volume includes excellent instructions on disassembly of the model 59 series.
Not all revolvers HAVE a model number- and those that DO do not have it marked on all revolvers. For NEWER Smith & Wesson revolvers, open the cylinder, and look on the part of the frame that is covered by the crane (crane connects the cylinder to the frame) You might see something like 10-5, indicating a Model 10, 5th change. But not all S&Ws had a model number.
