Make sure it is unloaded, then pull the trigger double action. It will tell you. If the cylinder turns and the hammer falls, it is a standard version. If the cylinder turns but the hammer does not move, it is the Single Action version. I don't have production numbers, but I suspect there were nowhere near as many Single Action Model 14s made as there were the standard version.
I checked, its a plain ol DA/SA 14-4
Single pinned front sight
Pinned barrel
Color case hardened (?) Hammer and trigger
