So the S&W box the 686-6 is on in post #5 is not the factory box for that revolver? The box's label does not match your SN#? The SKU# would be on it too.
From the date the Kernel gave above, July 2010, that would make your 686-6 one of the first ones as they had an introduction date on Oct-2010.
TALO was a distributor that ordered them, to their specifications, from S&W. The fact that it's a 686-6 with a 5" barrel & unfluted cylinder, from the factory, makes it one of the TALO special purchases. At that point in time S&W wasn't making that combination for their standard production revolvers (they do now because TALO dropped them from their line-up & S&W has continued them without "TALO" in the model's description/name). The wooden 3-5-7 grips were the last unique item for them, besides the SKU#.
Personally I (and others) didn't like the feel of the 3-5-7 grips. I took them off right away & stored them, never even taking a picture with them on the gun. I wouldn't let it bother you not having them.
The 3-5-7, in case you didn't catch it, is a .357 Magnum offered only in a 3", 5", or 7" barrel. Catchy.
