I have a 103CS and the Husqvarna book. The 103 is a great gun. Does yours have any letters after the "103"? If you let me know the letters and gauge, I can tell you how many of that model were made. Also, I think I can look up the date of manufacture if you give me the serial number range. Mike Covington (above) sets it out pretty well.

Take care,
Mike
