I've done some research and I can't quite seem to come up with any solid dates on the pistol except it is most likely post 1915. I purchased it at a pawn shop and it had quite a bit of surface rust on the barrel and the back of the grip frame where a palm would have had direct contact with it. The gun itself is old, the question being how old? It is chambered in .38 Special.

The serial numbers on the cylinder and frame star out with C 330 and three last numbers. I don't know what the C means.

The serial numbers on the swing out for the cylinder and the inside of the frame (they butt up against eachother when the cylinder is closed) look like this

Any ID help would be greatly appreciated.
