Working from memory only here, so no definitive information on dates or model designations. Norway adopted the Colt 1911-style pistol shortly after WW1 and produced the pistols on Colt-provided machinery under license from Colt prior to WW2, with production continuing under Nazi occupation during WW2. Overall production was, at most, several thousand pistols. These started showing up in the US during the 1960's. They are essentially the same as the pre-1911A-1 commercial Colts and all parts are interchangable. Relatively rare and somewhat desirable for collectors, with condition (including all original parts, etc) being the primary consideration for value.

Colt's actively marketed the product and made every effort to set up production facilities in countries that wanted to produce these pistols under license (and pay royalties under those licenses). Norway was one taker, Argentina was another (the Argentine version was essentially a copy of the later M1911A-1).

I apologize for not providing more definitive information, but this is all easily found on various websites. Hopefully this information will lead you to more informative sources.
