You have a K frame serial number associated with a J frame revolver. It is possible that the factory made a mistake, but, I doubt it. Your Model 36 serial number should either be all numbers, start with a J, a number in front of a J, or three letters. A new 36 you describe will retail in the 600-650 range. Without more of a description, your value range can be 250-500.
With the brief description that you have supplied,I would say that you have a SMith and Wesson model of 1905 4th change revolver.
Use a magnet. If the gun is nickel plated, a magnet will stick to it.
