Well, I honestly much prefer when the stuff is all together in the sticky so the info stays together.
The 1900 was a modern revamping of the 1640, to use modern steel stock bar instead of forged receivers, for one, and reduce the manufacturing cost of the proposal without sacrificing the quality. So, instead of forging alloyed steel of the 1640, wich process is even more expensive than working the old M94/96/38 low carbon steel, they decided to use normalized stock bar and machine it, then, heat treat it, like it's normally done for almost all receivers today.
The 1900 are definitely of the slickest action even made, there's no doubt. All through the production, the material quality and craftmanship is equal to what was produced at the original HVA plant. The finish was also quite the same from 1967 through 1979.
Then at the end, it's a matter of what you prefer.
The Zoli made 1900 are still quite popular in Sweden today, they even manufacture a "Husqvarna" version, with a schnabel and bavarian (piggy back) stock.
Sweden have changed the gun laws, but also the hunting rules. And since the average Swede can't own two rifles of the same caliber and is restricted to 6 guns in total, all the other stuff was sold back to gunshops. The younger Swedes who want to hunt or own guns want "modern" guns, they don't want their "grandpa's" antiquity. Also, in Europe, the way they hnt is different than ours, they don't go very far in the outbacks like we do, most of the time, they hunt clean places, so they can have more luxurious firearms. You don't find a lot of plastic stocks in there.
All that being said, the Zoli 1900 is not in the same class as our utility guns, so that's why, like many other European manufacturers, they don't sell that many in America. The Swedes, when they're not owning a 1900, Varberger or alike, tend to prefer German guns with nice woodstocks.
The young ones are not really interested by the old, cheap workhorse with a beech stock...
