Mannlicher Schoenauer M1903 7mm Carbine: Identification & Value

Question
I just bought an old Mannlicher Schoenauer M1903 7M/M carbine. It is in beautiful condition. How can I find out the year it was made and the value?

Answer
Hello Spencer.
  If your MS is a Sporting model, I might be able to help with a manufacture date. I will need the serial number to find it. I can say that the original 1903 sporting rifle was discontinued prior to WWII. Values depend on so many variables, but I have never seen a MS Sporter go for less than $600 and it was in pretty bad condition.
  Just do a follow-up with the ser# and maybe a picture. I will be glad to help all I can. Charles Gage
