Gruss Alte Schwede,
Vieleicht wir ein Norwegischen kategorie brauchen?
In broad terms it can be said that from it's "modern" founding in 1628 until 1814 the Norwegian Army received its weapons from/via Denmark, which is why the category "Dänemark/Norwegen" fits for this period.
The "Kongsberg Waffenfabrik" was established 20. March 1814, a month after the
Kiel Treaty of 14. January of 1814, where Denmark ceded Norway to Sweden (Norway and Denmark had been under the same king/queen since 1389/1397). However, the treaty was rejected by Norway, gathering representatives from all of Norway to establish it's own constitution by 17. May 1814. Sweden with King Carl XIV (Bernadotte) responded by invading Norway on 26. July the same year, forcing Norway into a union with Sweden (which lasted until 1905), by the
Convention of Moss (peace treaty) of 14. August 1814. However, although Norway had to accept the Swedish King Carl as their new (common)sovereign, Norway was allowed a status as an independent nation state with it's own constitution and parliament. Therefore, due to different production and different nation states, it is not relevant to put the "blankwaffen" produced in Norway between 1814-1905 in a category together with Sweden. Although some models, like the Swedish M1842/47 Cavalry Sabre and the Norwegian M1845 Cavalry Sabre are more or less identical, most models are not. On the other hand, collectors should be aware of the similar models (although with different markings).
As far as I can see from the forum, the periods before 1628 may be less relevant to specify. However, if this is required, then there are three periods which stand out. The first until 1389/1397 may be divided up again, but in broad terms could be described as the Viking- and early Medieval age. The next could be the time of the period (effective/real) Kalmar Union with Norway, Sweden and Denmark under one King 1389/1396 - 1434 (officially it lasted until 1591, but Sweden was out of it several periods from 1434). The next period would then be from 1434-1628 with no/less common equipment between the Danish/Norwegian armies.
As a conclusion, may I suggest a separate "Norwegischer blankwaffen 1814-1940" category?
Gruss,
Trygve
PS. I would have loved to be able to write this fluently in Deutsch, however, if I had tried this now I am afraid it would not have been fair to the German Language
