That would be a Victory model made in 1942 for the military.
The nickel is not original and pretty much destroys it's collector value as does the lanyard loop hole being plugged.
S&W's production during WWII was limited to supplying the Military.
That would be 1952. It should not be model marked.
How about a .357 Minnesota State Patrol XXX
450 made on the model 66 with a 4" barrel with shield on side and "State Patrol" on the frame.
SW Model 59, Serial A179xxx
If all it says is 59 then it is a standard 59. A 5906 would be stamped 5906 and so on.
