At one time or another I've owned at least one of everything on that page. Many of them came through International Firearms in Canada then were distributed to Canadian/US brokers and dealers such as Ye Olde Hunter and Lever Arms.
That Norwegian really brought back some memories. They never did come in significant quantities. Many were without any finish and had seriously pitted bores. Some even had what appeared to be Waffenampts.
I bought two. I was lucky enough to be in the International warehouse to pick through a bunch for the cleanest and of course best bores. They were slathered in grease but a quick patch through the bore cleaned them up enough to check bore condition.
This was the amazing thing. The Norwegians were ANAL about matching numbers one every part on the pistols. The only parts that I couldn't find numbers on were the grips and grip screws. Every other component had a matching number.
The two pistols I bought were OK shooters but definitely not any better than a US 1911 in similar condition. They were also about twice the price of a US 1911 at the time. I sold them a decade later. I don't think I shot 20 round through either of them.
The one pistol on that page I do miss is the Astra 400.
Those were incredible times to be able to pick up and learn the differences between the handguns issued to different nations.
One thing to keep in mind, those prices represent a pretty substantial portion of a weekly paycheck at that time.
Another thing, a lot of those firearms were not nearly as nice as those in the pics.
