I would look into it even if you think I am right. As all I did was put in "Taurus .357" in the search bar on gunbroker then look for a six shot .357mag with squared wooden grips. Dont take my answer as a professional opinion...lolazgunnut01, I'm sure jwernecke is correct. But if you want to be sure, call Taurus in Miami and ask for Customer Service. The serial number of Taurus revolvers is usually stamped on the right side of the frame ahead of the trigger guard. With the serial number, Taurus Customer Service can go into the computer and tell you the model number for certain. This can be important if you are registering a firearm. The authorities can be awfully fussy about that, even through it's the serial number they go by.
I just did that for an old Taurus revolver generally similar to the Model 66, but was told mine is so old, the computer doesn't have the model in the system!
