Yours was made (as marked) in 1923. There were 1660 made that year. It was in a shipment (SNs 3701-3750) shipped 10 November 1923 sent to the main arsenal (Hovedarsenalet) in Kristiania, Norway. As of 1939 it was issued to the 3rd Infantry Regiment.
It is a gorgeous gun, I am not a value expert but, it would depend on all the parts matching and they are prolific in these. Attached is an example of what my 1927 was supposed to be marked with, I believe yours should be so marked as well.
