They've done some interesting things, and licensed their name out for other ventures.
The pic above shows a CS tear gas cannister, they used to make a line of police gas accessories and guns/launchers to shoot them out of. There was even a marine "line" thrower made. They also made the pellets for their air gun line, three tins shown in the pic. They also were in cahoots with Fiocchi in the early days and made S&W branded ammo, rifle and pistol, in the pic there are a couple plastic pacs of rifle ammo (.270 Winchester IIRC), also Co2 cartridges for their air guns as well. Even the pocket protector is S&W branded, as well as the key chains. Even Zippo got into the game with their licensed lighters.
In the pic below, there are some empty cartridge cases for reloaders, as well as the licensed metal truck toys.
Can't forget the line of golf clubs made by S&W Golf company, a licensing deal that ran for a few years back in the 2000 timeframe.
